gReader Comments 4.1 adds Disqus commenting system to Google Reader. With this Firefox extension or the Greasemonkey script version this sweet little toll will let you comment using Disqus without having to leave Google Reader.

What's even better is any entries with any feed can be commented on regardless if the original site has Disqus integrated or not.

Remember you can either use the Greasemonkey script or the FF add-on.





A big thanks to Paul Arterburn for creating this script
