The agenda for this year's Rapidminer World (formerly RCOMM) is fast filling up with some great speakers and presentations, check out the agenda here. If you're a student, you can get special pricing with a current and valid ID, so you have no excuse to come!
Why am I pimping this? Because I had an utter blast at RCOMM 2010! I met so many cool people there and I got listen to exciting applications and use cases. Rapidminer users were developing processes and applications that the world is just realizing its potential, how cool is that? To be on the cutting edge?
You should go, you won't regret it! I'm going to be there myself, so come by and meet the team. I'll buy you a beer!
