Ghostcrawler has finally said on the forums what I've been saying for a while here on WoW.com and elsewhere: using blue text on the forums as a way of disseminating information is "a strange way to communicate." He's been appending the words "[Not tracked]" to some of his posts so they don't end up on the official "bluetracker," because a lot of what he posts is just silly and fun and not to be pored over and examined (especially without the context of the other posts around it). But all of those posts are still picked up by the unofficial bluetrackers that many players follow, and he laments that it's annoying to have people jump in on threads without reading all the context: "you end up looking like a real jerk half the time."
I would never call GC a jerk, but it's clear to see what he means -- sending out information via official posts on the forum is something Blizzard has done for a long time, and it's really a bad way to go about it. To their credit, they've been trying lots of new things lately, from official interviews to class Q&As and just plain releasing official information on the site. But I've always thought (and still think) that the company could use an official blog -- back when I was playing Dark Age of Camelot, I really enjoyed all of their work on the Camelot Herald, and I think Blizzard would benefit from something more like that. They do have a section for official news on the front page, but that's mostly licensed items and marketing information, not actual updates to the game.
