The guys (no gender implied) at AdRants are big fans of Twitter:

“Writing on Entrecard Graham Langdon makes the argument Twitter will be bigger than Facebook. He’s right. Twitter is many things but it lacks the baggage and some of the “creepy” aspects of Facebook. All within 140 characters, Twitter is IM, email, mobile app, chat room, focus group, news source, a wall on which to bounce ideas, a research resource, presence indicator.

It’s usually the simplest of things that have the most value. Facebook is bloated. Twitter is Internet Lite (I refuse to dub it anything with a 2.0 attached). It’s a simple but ever so powerful interface that brings so many things together and functions as a jumping off point to an endless collection of resources and information.

It’s pretty much guaranteed you’ll interpret this as idiotic puffery but until you use Twitter, really use it for a while, you won’t really understand what you’re missing and you don’t realy have the right to comment. Seriously. Give it a try.”

I confess I’ve given up trying to explain Twitter. And it took me more than a year to come around.
