I've looked around on the Sites overview of Stack Exchange and noticed there is a site for code review, but none for (blog) article review. I myself always look for a couple of proofreaders for my articles, and I think I'm not alone. An easy way to find proofreaders, or a platform to use with your current proofreaders to get feedback in an easy format, would be greatly appreciated by me, and I think others as well.
I did find the Writing Exchange on the sites overview, but its description does not seem to closely relate to what I'm looking for in particular. On Area 51, there's the Writer's Exchange, which seems to relate more to what I'm looking for, but I still feel my particular interest is not on topic for that particular site.
Assuming I can get such a SE site started, how would I go about it? What would be a good way to gauge interest in a SE site like that?
