I've since signed up and started following a few people (initially, just the cast of Questionable Content.)
But as you can see from my profile, I still don't "tweet".
And I'm still not convinced of Twitter's value. What exactly was I 'missing out' on?
Well personally I have found out some things about some of the podcasts/podcasters I follow, that wouldn't have known otherwise. like I didn't really care much for JC Hutchins filler after 7th Son, but without twitter, would probably have missed the whole Personal Effects thing.
I also follow, Al Jazerra News, VoA Special English, and BBC Learning English, which have been helpful when needing current event info for my English Classes. You can follow many other news sources, if your someone like me who doesn't watch much TV or read a daily paper, it's a way to stay current on what's happening in the world.
