1. What do you propose to do? [20 words]

rbutr connects webpages to rebutting webpages, providing easy access to an opposing perspective and ability to follow cross platform discourse.

2. Is anyone doing something like this now and how is your project different? [30 words]

This looks like a really good idea, although its use would depend on how many people were using it. I like the idea of reading articles in the mainstream media, and being able to quickly see what other people are saying about them. Hopefully rbutr will be a threat to bad science, and allow people who are not very technologically advanced to read alternative opinions. It would be good if rbutr gave a number of posts referring to an article as well, so that when a particularly bad one was written, users would be able to see how many people were critical of it.
