I enjoy Twitter enormously. I don’t follow celebrities much, mostly
(1) Arts organizations & Movie sites to read articles, listings, and other upcoming events, especially since keeping track of everything in the Bay Area can be tough
(2) Ordinary people. There’s something about the 140-character format that really nurtures creativity-though-economy. Try telling a joke, or writing a poem in that frame. It’s hard, but when people do it well and often, I find it worth following.
I’ve made some very good friends on Twitter, because (something I don’t remember seeing in the thread yet), beyond the Cocktail Party angle, you can DM (Direct Message) privately and have extended conversations that way. A bit like Kik, except w/the character limits, I’ve gotten closer to more people more quickly there than any other online board or application (including here).
I’m on FB but very rarely go because I find it way too glurgey, and more difficult to wade through one’s timeline. Twitter moves faster, is far more irreverent and subversive, and racier, too. YMMV on whether that matters to you, there may be people who exclusively post “Arrived at the mall now. What should I eat?” but I don’t follow those people either.
The one thing I find most hilarious about Twitter is how it’s portrayed in the media. Whenever a news network publishes a Tweet by an average person, it’s invariably a really really bad Tweet. I read so many that are witty, trenchant, blistering, or excellent at crystallizing an argument, but you never see those represented. Instead, it’s some dumbass saying your usual dumbass thing. Maybe that’s what a lot of Twitter is, but that’s not where the appeal lies with me.
Just my $0.02.
