OK, you land on a forum and browsing the forum sections to read some topics. What makes you happy there that you think it is a good forum and you should join and participate there? Do you see the total no. of posts/topics forum has? Do you see how many users are online? You like the quality of discussions? I know another webmaster forum wherein "I bet you" there is no quality content as compare to WG but there are more members online and more topics there. I want to know your opinion on what makes a forum useful and successful in its niche?
