• The documentation is really poor.
  
• Everything depends on entirely on contributors. Contributors need more juice. The main way to do this is feedback. Home nodes should have a list of nodes and writeups by that user, along with their current vote standing.
  
• The two writeup limitation is serious - especially if a node gets two junky writeups. One way to address this is to have a "see other writeups" link, followed by a vote for the new writeup to replace the old.
• Random isn't.

The whole documentation thing is because sometimes I would just rather use Everything than document it.
