Open Access Crowd Based Publications (StackExchange like)
Instead of anonymous peer-review, every member of the forum can comment and rate the publication. Is there something like this out there?


Yes.  The forum is called "the academic community," the comments are called "what they say about your paper in their paper," and the ratings are called "citations."  They are not anonymous.  Actually, citations alone are misleading, since they can be negative as well as positive.  The real way to determine if your idea is good is to see if people use it to build new, interesting ideas / explanations / products / companies / whatever.  (I think they call that "impact?")

In other words: publishing is the easy part (these days).  Getting people to say good things about your research is the real challenge.

I do think you are wise to think about publishing in open-access journals—and not for some self-righteous political/philosophical reason.  The real reason for making your paper freely available is: more people will read it!  Plenty of interesting people in the world live behind the Great Paywall of Academia.
