I've gotten into a habit of checking/posting on it several times a day. I even have an app tab setup in Firefox so I can keep track of my timeline and whatnot, not too mention I use the app on my phone quite a bit as well. I don't post a whole lot, as I don't typically like to post just random stuff. It's immensely helpful for me because I follow a lot of people and websites that post web design tips and tutorials and stuff. I also tend to get a lot of my news from Twitter because stuff happens so quickly on there, due to trending topics.

I too get a good portion of my news from twitter. News on there moves so much faster than most sites.
