I’ve used it for about a year and I’ve gotta say, Twitter seems a bit useless. I mean sure you may think it’s cool to let all your “friends” know what you’re doing at every second of the day, but in reality no one cares. I don’t know maybe it’s because I’m not a power user (in fact I hardly use it at all. On average I tweet once a month) but I just don’t see why Twitter is so important. Facebook has the same pointless “I’d like to let all my friends know everything I’m doing” feature. If you truly had friends, you’d call them and ask if they wanted to hang out. Or better yet they’d call you. Don’t resort to sending out a general notification to everyone in the hopes that someone will reply.
