I can't say that I use twitter much. I joined because I thought that it was a neat idea. I do not have a web capable phone so, in order to update, I have to go to the Twitter site and do it from there. I am usually busy with other things and do not think about updating. Enter "Twitux". I happened upon twitux while surfing and searching one day. I installed it thinking "this looks interesting!" Now twitux is a permanent fixture on my desktop and I update my Twitter quite often. Here is what twitux looks like on my desktop ..
At home I use mainly Twitux as well...also have gTwitter installed but it's not as strong. At work it's Twhirl. I'd also use my Blackberry for sending updates but my cell provider likes to charge me $0.25/message...lame. Do you hear that Rogers? Lame.
I don't get twitter. It's like facebook updates, but... that's ALL it is. I have an account, though, because I had to sign up and follow someone in order to win some prize thingy she was giving away.
