That video represents why I would put on the conferences. They were fun. We had a good time.

Personally, I would suggest staying local and attending or help organize a local PUG day for PostgreSQL. PUG days are the best in small conferences. You are meeting with many locals, quite a few contributors usually show up, and you get to go home at night. The content is always top notch and chances are you know many of the people there. There are many. We recently had them in NYC, DC/Maryland, and Austin. There is a Denver PgDay on the 26th of October (no website yet) as well.
