What people find attractive is usually unique to them, unless you are talking about shallow people.
The only way to know for sure is to start conversations, get to know each other, and see if you have similar stuff in common. Humour can be hit-and-miss but if humour is a big part of your personality let it shine, it may scare people off, or it may have the opposite effect. My advice (Caveat emptor

) would be stay true to yourself and if that doesn't work, you haven't met the right person (which can sometimes take a long, long time).
Edit: Ahg! I just realised this is L&D and
I've fallen for the trap 
The luv trap.
Meh, at least you have a hammock.
