If you could only pick one which would you pick? This would be very hard but I think I would pick Twitter but I am visual so love Facebook for all of the pictures but I do not like all of the silly quizzes.
I have to edit my answer. I'm now on Facebook and I like it too! Business-wise, I would say Twitter. Personal-wise, I would say Facebook. (More of my non-blogging friends are on Facebook and I've reconnected with people whom I haven't spoken with since high school!)
I am surprised by the Twitter lovers. I must be doing something wrong. I really don't understand some of the conversations and things going on with Twitter so it's a little frustrating for me. I don't like the quizzes and whatnot on Facebook, but I would choose that one because my non-blogging friends are on there. If Facebook would get rid of all the time-wasting stuff (only because I get tired of ignoring things people send to me) then it would be perfect! :)
At this point, I would say Facebook. Most of my friends are there but not on Twitter. FB seems to have much more to offer to me right now, and I can avoid the quizzes or other things without people knowing. Some people friend me on Twitter when I don't even know them, and then when I friend them back, I find out they post a lot of advertising on their Twitter feeds; whereas my friends on FB are posting personal things that I care more about. I am still learning the in's and out's of Twitter, so I hope that I can get more out of it as I move along.
