Reframeit!

Just downloaded the Firefox extension from Reframeit.
This is a great tool that allows you to comment on any page on the web, and see comments by others. It should make the experience of reading the news (for example, it apply to any content really) way more interesting.
I like that you can create group that are public or private to share your comments with people who care about one issue or another.
Another great step forward for us users...
