If you’re going to the PASS Summit this year, and I suggest that you do, you should be playing twitter bingo. How do you play? You go out of your wait to meet people at the Summit. If you meet someone who is on your card, you get their ‘code word’ and write it on your bingo card. The rules are explained over at SQL Server Pedia, but, basically, it’s just like playing bingo.
You can print out your cards at http://www.sqlseverpedia.com/bingo/ or pick one up at PASS at the SQLServerPedia/Quest booth.
