not to be cliche, but I live-breath-sleep-and-drink it. There's a really hot free-jazz scene emerging right now that we'll soon be reading about in textbooks, and a lot of great neo-bop fusion(for lack of a better term) happening all over(MMW, Flecktones, etc).. I can't think of anything more exciting than being a part of that.
There's also a lot of garbage now that jazz has been academised.. elitist attitudes and soul-less technique wizards, bred the same way academic instutions have been breeding their classiscal counterparts for ages(next controversial topic?

), but I guess that's the trend once something becomes commonplace.. same thing's happening with rock.
"Jazz" is such a broad category.. did you have something particular in mind?
