When I first heard about Twitter, I blew it off as a time-wasting site lacking functionality. Then I realized that it was the perfect opportunity to stay in contact with my many friends going to SXSW. For the first two days, Twitter could do no wrong. If I needed Redbull, I'd put out the SOS and receive a timely response as to where to get it. If I wanted to know where the hottest SXSW parties were, I'd consult with my Twitter.

By the following Monday, however, it had tapered off quite a bit, with many attendees going back to their day jobs. In the end, I really believe that it's only effective in large group settings, such as conferences. It enables people to let their friends know where they are without having to call in a noisy bar or restaurant. Otherwise, it's just another flashy website that we're forced to refresh throughout the day. If I want to read about your life, I'm going to want a summary, not a blow by blow.

Sometimes Twitter can take you by surprise, though ...
