Twitter is one of the most fun web apps I've ever used - if you've used it you know what I mean. I was skeptical before I signed up, but it turned out to be very fun. Anyhow, what I love about twitter is that it's a great way to get updates not just for what your friends are up to, but any kinds of updates. Using their API, I made a weather app (http://twitter.com/vanweather) that tweets the forecast for every day at 6AM. Check it out! I'll also be making one for Prague soon since I'll be there for the next seven months.
