Okay, so I just made up a new term “micro-app.” That’s the only way I can describe TheHotlist.com — it’s a micro-app. Basically, TheHotlist uses Facebook Connect to deliver a rich interface for your Facebook events. The interface is intriguing, delivering you a map and a calendar and showing you who’s attending what, where. It’s interesting and it may highlight something we’re going to see more of: deeper web applications built as massive mash-ups using networks like LinkedIn or Facebook as their core.
