The idea is that instead of parsing through disjointed material, searchers can lean back and have a story told to them about what they’re looking for. The Qwiki results page experience feels like watching a low-budget TV documentary with panned-across stock footage and a robotic voice. (Side note: You probably don’t want to learn how to pronounce things by hearing them on Qwiki.) Eventually these presentations will be created for many more topics, and be playable on a variety of devices.

Palo Alto, Calif.-based Qwiki, which just raised $8 million in Series A funding led by Facebook co-founder Eduardo Saverin, is hedging on the public release by calling it an “alpha.” But the company, which won the TechCrunch Disrupt start-up competition in 2010, says it has “hundreds of thousands” of potential users signed up, of which about 60 percent have been given access so far.

Qwiki CEO Doug Imbruce said in a phone interview that Qwiki has received acquisition offers already, and took funding from individual investors rather than venture capitalists so its founders could retain control of the company and focus on product rather than monetization.

Imbruce emphasized that Qwiki is not a search engine and does not seek to be comprehensive. He said Qwiki plans soon to build its index by letting third-parties input material for new topics, including profiles of individuals.

The App Store is now roughly two-and-a-half years old and offers software for a number of categories in 90 countries, ranging from games, news, sports, health, reference and travel.

Apple took advantage of today’s milestone to highlight several new figures: In addition to revealing that it now has 160 million iOS users in the world, it said there are more than 350,000 applications in the App Store that are accessible to users in 90 countries. Of that application base, there are more than 60,000 apps available for the iPad.

“The App Store has surpassed our wildest dreams,” said Philip Schiller, Apple’s SVP of Worldwide Product Marketing in a release. “While others try to copy the App Store, it continues to offer developers and customers the most innovative experience on the planet.”

Apple said the 10 billionth app downloaded was “Paper Glider,” which was purchased by Gail Davis of Orpington, Kent, in the U.K. Davis will receive a $10,000 iTunes gift card.

As a point of reference, Apple said in September 2009 that there were 50 million iPod and iPhone users, making the 160 million number announced today fairly significant.

This week, BoomTown has found an interesting chart to peruse about the loyalty people have for their smart-phone apps.

The takeaway for developers: Try to stay in Quadrant I!

In other words, Sally-Field-at-the-Oscars territory–it’s where they love you, they really love you.

To grok this, you’ll need to view the two charts below from Flurry Analytics, a mobile analytics and monetization tools start-up in San Francisco, from a blog post titled “Mobile Apps: Models, Money and Loyalty.”

Flurry used a sample size of 2,000 live applications and 200 million user sessions on the IPhone and iPod touch from Apple (AAPL), Google (GOOG) Android, Blackberry from Research in Motion (RIMM), and other platforms.

In Quadrant I are reference, news, and weather apps, which are frequently accessed and retained longer.

Quadrant IV is also good, with high retention rates–education, social networking, medical–but less frequent weekly use.

Here are the charts (click on them to make them larger):

I haven’t had time to do a full review of App World, but I tried it out for a couple of hours on a top-of-the-line BlackBerry Bold and a fast network connection. Here are my first impressions.

RIM’s store is clumsier to use than Apple’s (AAPL), but it works. The selection at launch is decent, but with some surprising omissions. The emphasis seems, at first glance, to be toward pricier apps. And, there are some limitations and oddities. Perhaps the biggest of these is that App World is only available for relatively recent BlackBerry models–the ones with trackballs instead of side wheels, starting with the Pearl, which came out in the fall of 2006. That means that millions of people with older models can’t use the app store.

App World has apps in all the major categories–Games, Productivity, Entertainment, News, Weather, Finance, Health, Social Networking, and so forth. The selection is broad. For instance, on the first day, it offers 166 games, 99 productivity and utility apps, and 69 reference and book apps. There are even a few of those fart apps that have proved so popular on the iPhone, something that seems so… unBlackBerry-like.

But there are some surprising omissions. There’s no dedicated Twitter client, at least none that either I or a RIM (RIMM) spokeswoman could find at this writing. There’s a Facebook app, but it’s the same rudimentary one RIM has offered for a long time. There’s no Google (GOOG) app, just a shortcut to a Google page in the BlackBerry’s browser. And there’s no app for shopping at Amazon (AMZN) or viewing Kindle books. No doubt these things will show up eventually, but given the competition and the time RIM has spent getting this ready, I was surprised they weren’t there at launch.

Still, I downloaded about a dozen apps and liked most of them, including the Bloomberg, Pandora, and Shazam apps. But a $2.99 Associated Press app didn’t work properly and looked crude compared with the free AP app on the iPhone. Shazam, which identifies songs playing nearby and gives you a chance to buy them, correctly identified several songs on the BlackBerry, but unlike on the iPhone, didn’t link to videos related to the songs.

The buying process is harder than on the iPhone. You have to download the store itself, then pay for any apps you want with PayPal, which requires going through a couple of screens each time. On several occasions, despite my fast, strong, steady network connection, app downloads stopped in midstream multiple times, And the least expensive apps are $2.99, about triple the cost of the cheapest typical paid apps on the iPhone. Indeed, I spotted a surprising number of $20, $30 and $40 apps on App World.

App World has other limitations and oddities. You can only save apps to the BlackBerry’s limited internal memory, not to a roomier flash memory card. RIM has made up for this by allowing you to also store your apps online, but that’s still a pain, especially when you’re not connected. And, oddly, the apps you obtain from App World aren’t located in the BlackBerry’s Applications folder, but in the Downloads folder. You can, of course, move them around, even placing them right on the home screen.

BlackBerry fans unfamiliar with the iPhone won’t care about some of these comparisons, of course. They will, and should, just be happy that their phones are now much richer and more versatile devices. And, in the end, that’s what counts. RIM is now truly in the platform game, which will make its products more attractive and could make its shareholders richer.

“The Internet is a great phenomena. I don’t see how the emergence of more information content on a network can be a bad thing for the personal computer industry. Will it cause less personal computers to sell? I think quite the opposite. Less copies of Flight Simulator or Encarta?”

In January, Wikipedia claimed nearly 97 percent of the visits that Web surfers in the United States made to online encyclopedias, according to research outfit Hitwise. MSN Encarta received 1.27 percent. Little wonder, then, that Microsoft (MSFT) is discontinuing it. The company announced Monday that it would stop selling Encarta software by June and would shut down the encyclopedia’s MSN Web sites on Oct. 31. “Encarta has been a popular product around the world for many years,” Microsoft said in a statement. However, the category of traditional encyclopedias and reference material has changed. People today seek and consume information in considerably different ways than in years past. As part of Microsoft’s goal to deliver the most effective and engaging resources for today’s consumer, it has made the decision to exit the Encarta business.”

Translation: Wikipedia ate our lunch–and our breakfast and dinner too. For evidence, one need look no further than Wikipedia itself, which updated its Encarta entry with the following passage within an hour of Microsoft’s announcement.

“Microsoft announced in March 2009 that they will cease to sell Microsoft Student and all editions of Encarta Premium software products worldwide by June 2009, citing changes in the way people seek information and in the traditional encyclopedia and reference material market as the key reasons behind the termination….Additionally, MSN Encarta web sites will be discontinued by October 31, 2009, with the exception of Encarta Japan which will be discontinued on December 31, 2009.”
