Upcoming events ?

Just found about http://upcoming.yahoo.com. I like the concept - looking for events, entering events so you can tell the world about thing you like attend. There seems to be export fucntions for ical, yahoo calendar and google calendar, which is probably the type of service I was looking for without searching specifically for it. The other neat feature I like about it is that I can tag my flickr pictures with a machine tag and then the picture becomes relevant to the event. As I'm attending fosdem this upcoming week-end, I registered the event (could not find anything by searching for Fosdem, and for searching events in Brussels). After searching by end (and not querying around for known names), I was able to find the registered fosdem events. I deleted the one I had created. I just hate services where search does not work.
I need to explore the service a bit more and see if it can be a bit more useful.
