Both places have their strengths and weaknesses.
Rocks House has become almost unreadable. Whoever said "Lord of the Flies" made an very apt analogy. There are a couple of the posters there that I enjoy reading who break down the x's and o's and obviously have played and/or coached the game for a long time at a reasonably high level . A lot of them don't know what they don't know and have never learned the value of an unexpressed thought. The more civil tone on the football board here is a big plus.
I find the other boards there are fine; for the most part, the snark and arrogance of RH is missing from them. NDN has dedicated boards to many sports that just aren't followed here and that's okay; you focus on what you want to focus on. I find their politics board superior to the political discussions here mostly because the one here consists of the same 4-5 people shouting over each other. This board has no one equivalent to BeijingIrish, a now 75ish year old who spent a career in international banking living all over the world and who can provide a view based on experience that few anywhere can match. Of course, this board has no ACross, a douche of epic proportions who has to be playing a character. No one can be that big of an ass and get by in life (he is one of the few who has earned an ignore from me and I read/post on many forums).
Regarding the post in question, that was a poster looking to get launched. The message had a lot of truth to it but you don't make your first post on any board in that tone without an agenda going in.
Anyway, my two cents.
Anyway, that's my take on things.
