I think I should probably go to the next API:World conference, because I'm working on a product called FormAPI [1]. Not sure if it would be worth it, though. I went to a tech conference earlier this year, and I didn't get too much out of it.
If you were working on a product like FormAPI and wanted to go to one or two tech conferences per year, which ones would you choose? I'm thinking about RailsConf (since FormAPI is written with Ruby on Rails), and maybe API:World.
