gReactions feeds comments into Google Reader

Google Reader is great for staying updated with favorite blog posts feeds, but when it comes to reading blog comments, it doesn't really deliver. gReactions, a Firefox extension fills the gap, and allows you to read comments from all over the web to your posts, directly from Google Reader. It collects comments from the blog post itself, FriendFeed, Twitter, Digg, Hacker News, Reddit and more. You can access all of this by clicking a link that gReactions adds to the end of each post in Reader.
