You have to take Bleacher Report for what it is, it's a place where regular fans can write and give their views on everything sports-related.
If you look on the right of the page, you can apply to write for them, and it is not so difficult to get in.
Don't expect professional journalism, just appreciate that BR provides this platform where regular guys, guys from the bleachers, can get a word in and have it read by a large audience.
There are some gems on BR but also some flops. I recall one writer remarking that the Modric transfer was a "surprise"; a surprise? It was building all summer, how anyone could've called it a surprise is beyond me, but, anyway:
Whether or not forums are read by important people, I assure you they are. I don't know how vital forums are to the overall machine, but understand that forums provide raw, honest feedback from fans. Absolutely there are professionals affiliated with pro clubs and offices that are always scanning forums.
Also, professional writers regularly scan forums for ideas and insights that they can use in their work.
Don't ever think forums aren't read, we have no idea who can be on the other side of the stuff we post.
