Someone named wowgossip on livejournal (though I think her character -- I'm assuming she's a woman, though that might be wrong -- is named Mary Sue, like the lead of so much bad fan fiction) is conducting a pretty exhaustive tour of roleplaying on the servers, both good and bad. As is clearly stated, this is not a review -- it's more of a "state of the game" of Warcraft roleplaying, so the good, the bad, and even the ugly are included. She's already stopped by Argent Dawn, Blackwater Raiders, Earthen Ring, and Moon Guard, and Sisters of Elune.
The sights range from the disgusting (you get offered to cyber by just being a lowbie and hanging around Elwynn, apparently), to the boring (there is some really, really bad vampire RP), to the fascinating (some of the character descriptions are very well written, and use some commonplace ingame gear to portray a character's backstory very well). There's no judging involved -- it's basically a (pretty) objective survey of what RP players are doing on RP servers lately. Even if you're not an RPer, it's an interesting read (though some of the images and situations are NSFW, depending on where you work).
There's more info in a Q&A on the journal, including a plan to possibly do some group RPing, but just the idea of surveying what's out there is cool. There is so much happening on the realms (in terms of RPing and grouping and PvPing), and even here at WoW insider we can only document so much of it. Definitely cool to get another look inside what players are coming up with (no matter how weird or boring or wild) on the realms.
