PowerSwitch

Anyone used this yet?

rbutr is a plug-in (Firefox/Opera/Chrome so far) which tells you if an article you're reading has been disputed on the internet. It could be an immensely useful time-saver.

You don't absolutely need the plug-in (handy if you prefer Safari) as you can check any page you're viewing by adding rbutr.com/ before the page's url.

I would be very cautious of adding this sort of app, too much delegation of critical thinking.

'Community led' criticism is interesting, but which communities? I like to read first and cross-reference later.

It's just another tool.
