I've seen other people doing it, and also came with the idea on my own, but a much better way of featuring peoples articles is just link to the articles in question.

If more people post some links with the blurbs to even a couple of articles that they feel are undervalued, then they are sharing their own reputation, readers and the like with the author. Without actually taking SP/SBD.

Besides, once people who write good content are recognized, and your own stuff falls through, you might get some of it in return. Which should be really cool!
Oh. It also build the community. Which is the actual idea behind that.

I have a post that outlines the ideas about all of that here, but it basicly says all that was in the comment, so it isn't necessary to check it out. Also, I think it is somewhat less coherent thar what I write in the comments. But as you said in the article. Promotion! :-D
