Well I wish I could say that I used twitter for news or to connect with people on a daily basis, however that is just not the case. I use twitter every now and again, but usually it is for telling people about new content that I have created or found online. I like using it as if it were a loudspeaker, but not very often am I there to "find" or "do" anything that it is meant for. The 140 characters kills me, it really does. The only real communications that ever happen on this site for me, is getting people off this site, so we can actually communicate like real people. I am looking forward to some other responses, because as much as I have used this site for marketing in the past few years I have yet to see why it is so popular. Even on mobiles, I don't get it, you already have text/mms capabilities that are far beyond tweeting and using them you don't have to hope your friends are using the same service or have a twitter account, to me twitter just complicates connecting with people and business online.
I guess I do pop in and look at the trends every now and again to see if I can find anything useful to my niches...but that's about it.
