I'd say FB as well, although I've never really used Twitter. ^^; I like it for similar reasons as Muffins and I find it's a great way to reconnect with people and keep up with what's happening in their lives. Getting lazy and losing touch with people is so incredibly easy, even if you think you have the best intentions to make the effort to stay connected.
But yeah, the stalkery aspect of FB isn't that great and I do think some people get to be a little too dependent on FB/social networking site at times. Yesterday, just after I downloaded an update to the FB app on my phone, the program kept crashing (great "update", huh? >.>). So, I took a look at the reviews to see if anyone else was having this problem and they were. One of the reviews said something to this effect: "The program keeps crashing! How am I going to stay connected to the outside world now?!
" I had to lol at that. Of course, it may have just been a joke, but I worry that people
really think this way sometimes.
