Welcome to NewEnterprise, the latest in the ever-growing stable of offerings at All Things Digital.

I am Arik Hesseldahl and I’ll be following the world of information technology with an emphasis on the enterprise. This is a deliberately loose definition that encompasses a lot, so I expect I’ll have a lot of room to roam.

Consider for a minute all the different threads that can reasonably fall under the umbrella term “Enterprise IT”: Everyone loves Twitter and Facebook and Google, but when some part of them fails to work right, phrases like “Fail Whale” enter the popular lexicon, and careers, reputations and investments are all at risk.

When they do work, the people who assembled all the hardware and software become the unsung heroes. I’m fascinated by both scenarios, because in their own way they’re both great stories that others can learn from.

You can expect me to pay a great deal of attention to developments in the burgeoning cloud computing industry, and in the traditional enterprise IT business of selling computers and other products and services to large companies.

Beyond that I’ll be looking deeper at the chips and other components inside them, and the companies and people who make them.

And I’ll also be keeping an eye on issues relating to computer and network security, an issue that has suddenly taken on significant heft, as computer worms have evolved from stealing credit card numbers to attacking nuclear plants.

Plus, I’ll be on the lookout for new start-ups aiming to change the way things are done in the workplace.

I’ve covered technology for more than a decade, most recently for Bloomberg Businessweek, and for Forbes.com before that. In those years I’ve learned to treat buzzwords and hype cycles with suspicion and to question the so-called conventional wisdom wherever possible.

So, I promise to tell you what I think is going on in straight and simple terms, and in a jargon-free manner.

In short, I think we’ll have a great deal to talk about. And that’s where you come in. I’d like to hear from you. Give me feedback. Tell me what I’ve missed and where I could do better and also whether or not you agree with what I’m saying, or where you think the next important story is.

Leave a comment here or send an email (Arik@AllThingsD.com).

What I need most are thoughtful ideas and feedback from the people on the front lines at tech companies, and those making tech-related decisions at non-tech companies.

Remember those unsung heroes I mentioned before? They’re you. And NewEnterprise is nothing without you.

Facebook’s Lexicon counts “occurrences of words and phrases” on its Walls over time.

Facebook, which had tried to buy Twitter late last year, has recently done a redesign that some critics are saying is too much of a panicked reaction to the hype around the microblogging service, although Twitter’s audience is just a tiny sliver of Facebook’s.

Still, Twitter’s becoming the digital trend of the moment, especially in the what’s-hot-today media, has to have last year’s golden child, Facebook founder and CEO Mark Zuckerberg, more than a just little irked.

Here’s the chart (click on it to make it larger):

Not satisfied to just entertain the masses with inane Vampires and SuperPokes, the social-networking site unleashed Lexicon on users this week.

It’s kind of like Google Zeitgeist except… well, it is exactly the same concept, all part of Facebook’s admiration of Google (GOOG) things, like, for example, as many of its employees as it can entice away.

As Facebook’s Roddy Lindsay described it: “We thought it would be cool to show trends on the public and semi-public forums across Facebook (also known as Walls). Today we’re announcing the launch of Facebook Lexicon, a tool where you can see the buzz surrounding different words and phrases on Facebook Walls.”

But, as much as I hate a lot of these juvenile time-wasters online, I do like the very simple Lexicon very much, especially in its ability to compare up to five keywords or two-word phrases at once.

Thus, BoomTown is periodically going to post word comparisons here, always using Britney Spears as the control word, since she has been a perennial champ on Zeitgeist for a very long time.

So, today, it is presidential candidates–Sens. Hillary Clinton, Barack Obama and John McCain.

As you can see, among users of Facebook, Britney holds up surprisingly well, even though she is going through a quieter, less-manic-head-shaving period of late.
