You know, I think the RWA experience really depends on the group you join.
I went to RWA last summer - did not know a soul except for some buddies online. I hung out with the other Pocket authors (who were so gracious to a noob that it made me want to weep) and book reviewers. Everyone was SUPER nice, I thought. But the interesting thing to me was...unless you have something written on your badge that equates you to published, people tend to ignore you. Which is funny.

Some people had a million chapter/conference pins but were not published, and they were much higher on the totem pole than me, who had a blank badge.
I also came away from RWA with the impression that Harlequin was the biggest thing. The people that went to RWA were looking to make a career writing category. Not my thing (too hard to write) but I admire the folks that can. Harlequin is big business at RWA, and a lot of the classes there are how to get published with them.
Went to my local chapter. Again, if you have lots of chapter buttons/pins/awards, you are far more important. There were several category authors at the meeting I went to, and most of the comments/questions in the meeting were about how to write for specific Harlequin lines.
I went with my friend who is a Kensington Aphrodisia author (erotica) and she loves RWA. Has been part of the local chapters for years. There were not a lot of erotica authors at the meeting we went to, but then again, there were not a lot of paranormal (my genre) or even single title, for that matter. It was primarily Harlequin.
I know the Oklahoma RWA chapter has a very active group of single title, paranormal authors, though. I imagine their chapter skews a lot more to those particular genres than Harlequin. Doesn't make it bad or good, just different.
To be honest, the thing I have noticed in my (admittedly small) experience with RWA is that they value activity in the group and contest wins more than anything else.
(I did ask my friend if she thought there was a bias against erotica in RWA and she said no, just that there was not a lot of erotica authors in the RWA chapters she'd visited. I didn't ask her about the RITA, though. I can't imagine she's happy about that, though. Why is there YA but not Erotic? Strange.)
