Like a lot of people, I find that while the talks are interesting, there are enough other things going on that are even more fun, so the talks definitely take a lower priority. I'd need 10+ instances of myself to have paid full attention to everything I liked at DC22.
I never bother with going to the talks while at DEF CON. Everything gets posted online afterwards, and there's enough going on outside of the talks, that I've never been able to justify actually attending them.
