An example of a site where a user publicly works on complex text?

Question

User interface

Hello!
Interested in specialized web services or any other with a piece of the following functionality:

• User publicly posts text for themselves and other users' ratings.
  
• If, in the opinion of the user, the comments / comments of users are of value to him, he somehow changes his text and demonstrates a new version
  

Generally receives help from the community. At the same time, the user (the owner of the text) received advice, and did not give editing over the document to others
