No advantage, really. Like I said I'm not trying to compete. However, in the eyes of Google, a sticky here that has the same topic as a post on another site would likely get much better rankings and higher traffic. Google bases most of it's ranking algorithm off of social engagement, that being not only shares on social network but, above all else, comments. And a thread is nothing more than a question followed by a million comments answering that question.
The only benefit of a site over a forum is it is easier to optimize the page/post for Google. You can set the alt texts, headers, body copy, etc. So a well put together post with a fair amount of comments would do about as well as a forum post.
