Great idea, novel execution.

However - you might want to stick some validation or a moderation step in: the first in the list is currently "necenzurat is looking for help with getting laid. In return, they can offer their help with massage.".

Unless, of course, that is the real underlying intention of the app...

EDIT: After a short think, I think it would be nice to use a similar auto-complete "tag" entry system a la Stack Overflow. This would make entering any number of skills a great deal easier than just a text field.
