Well, that's a pretty broad question
First, remember this is still the world's oldest profession & we aren't in any danger of that changing anytime soon
That said a couple of themes (in all cases I'm generalizing):
*We are still in the midst of a recession. NYC in particular has been hit hard. Some "banker hobbyists" now actually have budgets

(or in the case of client entertainment no longer have budgets for this kind of thing

)
*More touring gals (nationwide) seem to be reporting poorer than anticipated results. Some are even backing away from tours.
*In general it seems there is an overall downward pressure on pricing in the "advertised" market. That isn't to say some largely UTR gals with regulars aren't doing quite well.
*The ad content in general seems to have gotten quite brazen with much more discussion of specific acts or "menu items," yet another symptom of a very competitive market.
