I've seen that site a few times.... and have some issues with the guy that runs it... don't really want to get into it, but that's the reason I've not posted links to that site before.
He has one guy that does some writing for him, I think his name is Tim Hicock... that dude is amazing!!
What I get when I'm reading the comments on the site, is that the guy that owns the site writes a bunch of them. If not he heavily edits them! Try a comparison with any site allowing comments, you will see that discussions go off topic by a huge margin. Then some folks say just something brief, while others write a book.
Then again, maybe it's just me....
