Well, people tend to dislike it if you submit your own blog posts (you're biased, too wordy, trumpeting your own horn, etc.).
So this would be a place to hold virtual design reviews: ask people to look and provide objective feedback; the comments thread would function as the Q&A part between the hacker and the community of reviewers.

wouldn't it be simpler to just decide that it's ok to submit your own posts? some people have done that already and it seems fine to me: they're among the best links here.
