I have a Twitter account. I have tried several times to tweet regularly and it just doesn't happen. Too many social networking sites anymore. I have Facebook which is pretty much regular for me. Then I have Twitter which I'm rarely on, then I have Google+ which I don't use, then I'm on Foursquare which I don't use, then I'm on LinkedIn which is another waste of time, and now I signed up for Instagram which is such fucking redundant garbage I don't see the point.
I have a twitter account...I use it to contact others...It's great for getting info to people it would have once been nearly impossible to contact...Battlefield 3 uses twitter to report game issues/servers down. Torrent sites use twitter to report tracker issues. It's great for finding out if it's just you that's having an issue or everyone. I love the feed Massholesports...I joined in Jan of 2009, have 1,000 tweets...and never do I think that for one second people truly give a shit about what i have to say http://www.whendidyoujointwitter.com/
Luckily, I don't tweet myself. But all the police and fire agencies, along with a large part of the media, get their information out through twitter now. Instead of having to wait to hear things on a scanner or do a beat call to the state patrol, I learn about collisions just minutes after they happen.
It's perfectly easy to stay away from celebrity and teeny bopper horseshit. If you're a sports fan, twitter has become a great outlet for quick and inside news from beat writers and bloggers. I like ze twitter.
I use it mainly for news and to follow a few baggers...Facebook is more for family/friends and a few baggers have actually made their way to my friend list (and I've learned the translate function in Facebook thanks to Neon posting in the weird Hebrew language ...Twitter is more for me to rip on politics and dirtier stuff.
