Open space technology conference - any advice before attending to?

Question

I'm going to attend my first one OST conference (unconference) and I'm very excited. I'm looking for advice what to do to gain more experience. Should I talk about areas within I'm good at or technologies I want to know better? Any other advice?

Maybe it is a little subjective question, but sometimes after fact I have feeling that with the benefit of hindsight I think I would do quite different things, and I would like avoid situation like that.

Edit: After comments I must add some additional information:

• that will be programming unconference
• there will be "hands together" section - in workshop form - so we will be programming
• for me unconference seems like SO in real world :)

Well known example od open space conference is JavaPosse Roundup

Answer 1

I think you should talk about areas within you're good at, this way you can help people interested in those areas, and maybe get some instructive feedback as well, and listen to what others will speak about technologies that you want to know better.

I'm the unconference organizer at ZendCon next week - http://www.zendcon.com/uncon - and after I got a flood of email asking the same question, I just wrote up a post: http://caseysoftware.com/blog/so-its-your-first-conference
