I joined the bandwagon and signed up for a twitter account. It’s a way to update everyone on your whereabouts and what’s happening, except 160 characters at a time. Ideally, it’s updated using SMS messages. While it’s too short to really get any message across, if you “follow” another person’s updates, you develop a sense of their life.
It’s only been two days. I’ll follow up with a full review soon.
