From the official Google Blog http://googleblog.blogspot.com/2009/09/surfacing-forum-posts-in-search-results.html
Yea saw that...its good now...but now lots of forum and wasteful posts will be visible....hard to find good results now lol
Should definitely make things interesting. Though, I would think that it means that spammers will try to hit forums even harder now - because of the increased visibility they may get.
I find it interesting that Google is giving more weight in the SERP's to forum posts. They must see it as a good form of information, even though mosts threads are worthless dribble.
I like it for some things, but soon the will just display the friggin post in the results and there will never be a need to go to the website. No Traffic = No Business. this is what a lot of big media companies are complaining about, its content theft almost. Google have nothing without its website owners!
