Joe came up with the idea of commenting on comments and I think it's a good one.  Basically, commenting on comments (comm/comm) allows people to discuss and debate, as in a blog commentary section, with one comment building on the next. 

The way comm/comm will work on Rayt is that when you clicked a link in the Rayt comment banner, the dialogue box that would appear will contain a comment thread of the root comment and all the piggyback comments connected to that root so rayters can follow the conversation.  

Each comment will have it's own 1 to 5 rayting and will have its own seprate link in the Rayt banner.  The only difference between independent comments and root or piggyback comments is that independent comments will appears alone in a dialogue box but root and piggyback comments will appear in a dialogue box along with the entire comment thread.  

We think taking part in comment conversations will encourage people to participate in Rayt.
