Well, its been a whopping 3 days since I signed up for Twitter and a life outside of it is still very clear in my vision.
This is good news, but it leads me to conclude that unless you're Gerard Butler (or some other hot and sexy celebrity) or Barack Obama, the whole thing is rather silly. That is, of course, unless you have a horde of friends who want nothing more in life than to know what you're up to and must be kept up to date in some way other than direct communication with you.
Since I'm not a celebrity or a social butterfly, Twitter is just not something I see myself doing much with for now. Maybe when I am doing something interesting enough to update people on, but it's just gonna be another site I've joined but spend very little time using.
I will say that I think Obama's use of the service was total genius, and from what it looks like, he used it up until the very end of his campaign; his last update was Jan. 19th. As for Gerard Butler... well... it's good to see he's down to earth. :-D
