There's been an interesting discussion over the last few days about Twitter's reach. WSJ reporter Kara Swisher surveyed her dinner party and found out that no one there uses the micro-blogging site. Meanwhile Gina Trapani on Lifehacker is running a survey asking if Web 2.0 benefits only the tech elite.
Now let's look at the data. According to figures just out from Hitwise, Twitter is the 439th largest social networking site and 4309 overall. To be sure, growth is booming. But the site is still niche.

So all of the signs generally point the same way. Most of the social networking and online communities are definitely geek havens. MySpace, Facebook and YoutTube are three that have gone mainstream. So does that mean these smaller sites, like Twitter, are not worthy of a brand's time? Hardly.
Geeks are by far more influential than any other online contingency, except the big media. Geeks pass the puck from Twitter to blogs back to Twitter. Eventually it hits Techmeme, Saul Hansell at the Times takes notice and then the whole world knows.
That's why smart companies like JetBlue and Zappos are legitimately engaging on Twitter. It's becoming a front line for customer service. At a minimum, every consumer facing company should be monitoring the chatter. Even better, participating can cut problems off at the pass or even better foster evangelists. The numbers may never tell this story. For more, see Chris WInfield's mini case study.
