Tbh, I'm beginning to believe this is a problem more or less unique to this site, at least judging from my observations. Recently I started to post on a different site and have taken up posting my German stories on two different German sites. On all three of them I get much more feedback (both ratings and detailed critiques) than I get here.

One of the German stories was read about 3000 times, rated 76 times and I got 17 critiques, 12 of which were actually helpful (and encouraging).
