I frequent a sci-fi fan club in my city and from that group emerged a tiny writing workshop (6 members currently). The couple of guys who came up with the idea had heard that I wrote some small stuff and won a local contest, and thus I got invited. Every two Sundays we meet via Skype to comment on the stories that we've posted to our FB group since the last meeting. It has been helpful for me; we've agreed to be brutally honest with one another.
