Who thinks micro is the new black?  Hello Twitter!

I got a Twitter account a long time ago.  I did nothing with it and thought nothing of it. Really, I just liked the logo and site graphics (I love vector graphics), as I am a sucker for those things…  But recently, Twitter is everywhere.  I’ve been notified that people are following my feed (that will be a serious snoozefest!), Twitter is a GREAT way to market your brand (hmmm…I’d have to be convinced…), some big guys are leaving Twitter (that doesn’t bode well) and finally, SXSW real-time event coverage. Ah…real-time journalism. That makes sense. So what’s the Twitter deal?  Am I missing something?
