While not a roadmap, I'll try to list a few things I've been planning for near of far-term development into debatepoint. In NO prioritized order:

* arguments of "irrelevant" to go with "support", "oppose", and "comment". Irrelevant-marked child arguments would have the same effect as moderating an argument as irrelevant.

* direct stance moderation. ie. popular consensus moderation. The score wouldn't be derived from the arguments, but instant feedback from the user moderation. Maybe add a second triangle to represent this statistic.

* history tracking. cron job that frequently runs a script that keeps track of every modified stance over time. generate graphs to see how the debate has progressed over time.

* tag-based RSS feeds of points

* javascript routines to render tag-based RSS feeds dynamically on front page. This would be like start.com or google.com/ig, and would allow the user to customize which topics show up on the front page. Rico has a nice drag-n-drop library.

* CSS cleanup, site revamp. use subtle gradients. possibly make a non-annoying logo.

* user pages needs extensive work. add tabs for different areas like "arguments made", "user preferences", "points submitted", and maybe a "talk" like page like wikipedia has.. sort of a cross between a blog and a forum. Also, argument lists need to truncate redundant threads.

* javascript routines to create new arguments without reloading the page. Once you click "support", the thread should make room for the space to create a new reply argument. "preview", and "submit" shouldn't reload the page either.

* support for different RPC methods. json, xml-rpc, etc. see API for de.licio.us

reply on this thread any other things that I'm sure I most definately missed.
