That’s the conclusion Citigroup’s (C) Mark Mahaney reached after taking Microsoft’s (MSFT) new search engine for a spin and comparing it to Google’s (GOOG) and Yahoo’s (YHOO). The result: Google still delivers better results most of the time. In 71 percent of searches, Google either supplied the most relevant answer or tied with other engines. Bing did that 46 percent of the time.

But it’s worth checking out the results of Mahaney’s test to see exactly how the search engines stack up. For one thing, as he notes, Bing’s results are getting better as it matures–it’s only been live for about a month–and as it adds bells and whistles (for instance, it is catering to vanities of certain bloggers by including their Twitter stream in search results).

And Bing also performs better for at least two kinds of searches: Health and travel. So if you need to book a trip, or if you pick up a rash on that trip, you might want to think about Binging before you Google.

First, Mahaney’s methodology:

Over the past two weeks, we conducted 200 queries across the three major Search engines–Google, Yahoo! and Bing. Most of the queries we picked came from Google Zeitgeist, Microsoft’s xRank and Yahoo! Buzz, along with some personal queries. These queries spanned multiple categories, including Entertainment, Health, Local, News, Retail, Sports, Travel and Other. After conducting the same query across all three Search sites, we picked a winner based on: 1) relevancy of the organic search results; and 2) robustness of the search experience, which included factors such as image and video inclusion, Search Assist, and Site Breakout.

And his results. Overall relevancy (click to enlarge):

I tried the new iPhone Kindle app moments after it became available on Apple’s App Store (AAPL), and my first impression is generally positive. But first, let me note the key features of the hardware Kindle that aren’t carried over to the iPhone app. It doesn’t support periodicals. It doesn’t read books aloud. It doesn’t allow you to enter notes or highlight text, look up words in a dictionary, or perform searches.

And, if you wish to purchase a new e-book, the Kindle app sends you over to the iPhone’s Safari Web browser to go the Amazon (AMZN) Web site; it lacks a built-in Kindle store.

However, it is a solid basic app for reading books, and is especially valuable if you already own a hardware Kindle, as I do. In my brief tests, the iPhone app synchronized rapidly and perfectly with my purchased library of Kindle books on Amazon’s servers, and allowed me to retrieve a previously purchased e-book, without paying again, just as my hardware Kindle does. It also synchronized to the furthest page I had read in that book on my Kindle. After reading for awhile on the iPhone, I performed that process in reverse, and my Kindle took me to the same spot where I had quit reading on the iPhone.

This means that, if I were in line at the grocery store with my iPhone, I could read a few pages of my book, and then, when I picked up my Kindle at home, I could continue reading, starting from the same spot.

I also was able to buy a new book using the iPhone’s Web bowser, and Amazon gave me a choice of auto-delivering it to either my Kindle or my iPhone, which it treats as just another Kindle. I did so, and it appeared very quickly. I later downloaded it as well to my Kindle.

Reading on the device was easy. You turn pages using the iPhone’s horizontal swiping gesture, and you can change the font size on the fly, and create bookmarks, which then can be synced back to a Kindle device. You can view any notes you made on a hardware Kindle. And there’s a slider to quickly go back and forth through chunks of the book.

The only flaw I encountered in my brief testing: if you turn pages too fast you get a fleeting blank page or two.

In two key respects, using the iPhone app seems superior to using a Kindle. First, the iPhone’s screen is brighter, and supports color, so book covers and illustrations in my test books looked much better on the iPhone than they did on the Kindle. Second, the iPhone is smaller and thus much more portable.

The new Kindle app isn’t as full-featured as some other e-reader apps for the iPhone, which do allow annotation, searching, and so forth. But it gets the job done and it gives you access to Amazon’s large catalog, which contains more popular and current commercial titles than other e-book sellers offer.

If you’re an iPhone or iPod Touch owner who has yearned for a Kindle but balked at its $359 price, or a Kindle owner with an iPhone or Touch already, this new Kindle app is a good bet, even if it is bare-bones.

“I am coming to believe (industry self-regulation) is not sufficient,” said Rep. Boucher, chairman of the House subcommittee on communications, technology and the Internet. He noted that there is a need for a set of laws that dictate parameters for how companies collect, share and use online data about their consumers.

In its report, released Thursday, the FTC laid out a number of principles to guide practices for online behavioral targeting, in which a company tracks consumers’ online activities, such as the searches they perform and the Web sites they visit.

The latest: An announcement that advertisers who buy AdWords–Google’s main revenue engine–can now automatically buy mobile advertising, too. The company says AdWords buyers can choose to have their AdWords automatically show up on phones that support “real” Internet browsers like T-Mobile’s G1 phone and Apple’s (AAPL) iPhone. Here’s an example:

These ads will reach a relatively small slice of mobile phone users. But that population will increase rapidly, particularly if Apple really does start selling cut-price phones at Wal-Mart (WMT). Which means that Google (GOOG) really may be the first company to make inroads toward the supposedly-huge-but-so-far-mythical mobile ad market.

Release from Google’s Daniel Rubin:

Today, we’re announcing a new campaign-level option that allows you to extend the reach of your text and image ads to show your AdWords ads on the T-Mobile G1, the iPhone, and other mobile devices that have full (HTML) Internet browsers. This new option will now allow you to display your ads specifically on these devices, create exclusive campaigns for them, and get separate performance reporting. We hope this option will help you more effectively reach your audience with the right message at the right time.

G1 and iPhone ads have many of the same benefits as our standard mobile-format ads, such as allowing you to deliver mobile-specific calls-to-action and reaching your audience when they’re on the go. Showing ads on the G1 and iPhone also have additional advantages for your advertising. Users are performing a lot of searches on these devices, and searches are likely to go up during the holiday season. Last Christmas, the iPhone drove more traffic to Google.com worldwide than any other mobile platform.

Unlike standard mobile ads, you don’t need to format your ads for mobile phones to show your ads on the G1 and iPhone. Because the G1 and iPhone has full Internet browsers, you’ll be able to display your standard AdWords ads and landing pages on these devices without having to modify them.

With this new option, you’re opted-in to show ads on the G1 and iPhone, and you’re also eligible to show on additional devices that use full Internet browsers as these devices enter the market. If you want to change your settings to only show ads on G1s and iPhones or to not show ads on these devices, follow these steps.

If you’re running standard mobile ad formats, they won’t be affected, and they’ll continue to run on mobile phones with mobile (WAP) browsers.”
