As a reader there, I can say there is a lot of interesting material there, and a lot of talent, though you have to go searching. And that searching, along with feedback given to me by a somewhat successful contributor over there, is why I can't give it the highest review. There is no specific way to find the most quality and credible stuff. Also, they don't help their writers as much as they could. Promotion is basically up to you. When they highlight an article, that can help, but even when you submit to an assignment, the odds of getting featured are small and no one seems to know what can help you get featured. Nevertheless, as a reader or contributor, this is a viable outlet with a high profile.
