Less is more, they say, and Twitter takes it to heart. Twitter, the It social networking tool right now, is a micro-blog you can update 140 characters at a time, as many times as your fingers can pump out those 140-characters-or-less tidbits.

“The content that drives Twitter is a relentless stream of real-time personal status postings called tweets,” writes Scott Spanbauer in IT Business Canada. “‘Going out for more batteries,’ or ‘Feeling snacky, I think I’ll have a salad’ are the stuff of Twitter greatness–as long as tracking your friends’ ephemeral actions and mutterings is your cup of tea.”

With Twitter, you can post and receive items via the Twitter page, an application, IM, and text messages. Your tweets are archived on a personal page, they automatically show up on the pages of your friends and they can be routed to other sites like MySpace, Facebook and your blog, thereby allowing you, not only to chronicle what you’re doing, but to show the whole world what you’re up to.

If posting a blog made me feel like starting a conversation with the world, tweeting makes me feel like I’m in the middle of a huge party where everyone is having multiple conversations with everyone else at once. It’s a constant discussion of what people are doing, thinking, reading and planning that you can keep having no matter where you happen to go.

Twitter’s like the midget lovechild of a blog and a chat room. It’s simple enough that any non-techie can use it (including your mom!), it’s versatile, it’s mobile, it’s free and, apparently, in the irrational exuberance surrounding this far faster form of exhibitionism, it is also an ideal location to score n00dz from people you hardly know.*

Twitter has a page devoted to why you should care. It’s modest: “Why? Because even basic updates are meaningful to family members, friends, or colleagues—especially when they’re timely. Eating soup? Research shows that moms want to know. Running late to a meeting? Your co–workers might find that useful. Partying? Your friends may want to join you.”

But I think it’s more than that. When a storm was tearing through the Midwest and my friends lost internet, they were able to let everyone know, with a single text, that they were doing OK. Likewise, updates from organizations like Los Angeles Fire Department, the Red Cross Safe and Well, BreakingNewsOn and What’s Shaking? can be extremely useful in case of an emergency. For those on the go, Commuter Feed uses its Twitter account to collect reports about traffic and then arranges them according to area for easy perusal.

It can be incredibly fun, too. The level of entertainment you achieve on Twitter is in your hands. Some have suggested it’s only fun if all your friends are on there, like Facebook, but I don’t agree. Twitter is that missing link between friend-whoring that goes on at MySpace and the inherent elitism of Facebook. You can follow only people you know, yes, but why not reach out to people who can make you ROTFL with their daily adventures or the innovators in your industry?

There are plenty of sites to amuse you and help you find interesting people: Twittervision, Twitterverse, Twittearth, Twittertale, Twitterbuzz, Tweetmeme, Twittertroll, Twitterholic, Tweeterboard, Hoosgot, Twitstat, Tweetscan, Twitterlinkr, TweetStats, TwitDir, TwitterSearch and Terraminds.

Our species is, more and more, a nomadic, workaholic bunch, prone to moving around too much and working long hours. Twitter is redefining what it means to be “connected.” Its simplicity is what makes it so much more effective than its wordier, bulkier older siblings (MySpace, Facebook, LinkedIn).

There’s no better way to cut the fat than with a 140 character limit. In fact, I think any journalism student should be forced to spend his or her first year communicating entirely on Twitter.

According to Business Week’s Stephen Baker:

Do I Twitter because I’m lazy? A few times this weekend, I’ve sat down with a laptop and thought ever so briefly about blogging. But then I wonder if the blog post is relevant, interesting enough, perhaps a tad too self-focused…. Twitter, on the other hand, is a breeze. It can be irrelevant, nakedly self-promotional…. Long story short: Blogging feels more like writing a story, and Twittering feels as free as blogging used to.

Whether you’re getting fired or watching your wife give birth, Twitter can bring hundreds of people to the center of the action, often leaving conventional online news media in the dust, as it did when YouTube went down and London was shaken up by a quake. Even NASA missions may be tweeting soon!

In an article for The Guardian, political blogger Patrick Ruffini remarked on the instantaneous nature of Twitter, “Traditional news operated on a 24-hour cycle. Blogs shortened this to minutes and hours. Twitter shortens it further to seconds.” Its immediacy makes it worth its weight in gold. So much so that traditional news organizations have come onboard: NYT, Reuters, CNN Breaking News, BBC News and USA Today all have Twitter accounts.

Twitter can also be used to keep track of your iPhone’s location–or that of an iPhone’s owner, to improve communication and foster relationships in academia, confess your sins, and even to help you remember when to water your plants. Of course, for those of us who’re not that tech-inclined, there’s always Sandy, the electronic personal assistant, who just so happens to have a Twitter account herself where you can easily reach her.

“Some folks use Twitter like a bullhorn, and others use it like a walkie-talkie.” writes Chris Brogran, and it’s true. You can broadcast what you’re having for lunch to the world or, if you use an @ before another user’s name in a tweet, you can direct the message to them.

Of course, everything has its critics. As Andrew Lavallee wrote in the Wall Street Journal last year, “some users are starting to feel ‘too’ connected, as they grapple with check-in messages at odd hours, higher cellphone bills and the need to tell acquaintances to stop announcing what they’re having for dinner.”

The same article quotes Microsoft blogger and hypertweeter Robert Scroble: “Twitter hate is the new black. Some haters have already come around, but to tell the truth, they do have a good point. Do you really need to know that I’m eating a tuna sandwich for lunch? Probably not, although I’ve had more than one person come over and join me for lunch because I told where I was hanging out.”

Jack Dorsey, Twitter’s co-founder brushes off the critics: “Everyone says Twitter’s completely useless, I don’t want all this information. We check in later, and they’re complete addicts.”

Despite the optimism, some will never get it. Twitter’s not for everyone. When I enthusiastically told my husband I was following this really neat guy named Ryan Kuder as he was laid off from Yahoo in real time through his tweets, hubby gave an appropriately Corporate American response: 0h n0ez, more ways for employees to waste time and ZOMG, can you SAY serious information weakness?!?1!

To me, a certifiable twit in dire need of a Twittervention (is Twitter down? IS TWITTER DOWN?!), the worst part of Twitter is trying to explain its awesomeness to unimpressed non-users. Like Michelle Slatalla, who wrote a piece in the New York Times about trying to convert her three daughters and husband to Twitter, the resounding answer seems to be that I seriously need to get out more and actually, you know, talk to people.

DO NOT WANT!

I don’t care what they say, Twitter is not the social networking equivalent of crocs!
