You tend to get 10-15 one-sentence comments from different people, with very little in the way of conversation or debate. This is from two days ago:
The problem for me is that in order to read the actual article, you have to click through to the BB site. To comment, you either go back to FB or click one more button to get to the BBS here. It really doesn’t save any time and it’s obvious that more people commenting here have actually read the article. If I like an article, I’ll link to it on the main site so that I can share it with my actual friends rather than commenting with people I don’t know.
