I’ve been using the Cocomment extension for Firefox since mid-August. In case you’re unfamiliar with Cocomment, the service lets you track your conversations around the web- “coComment keeps track of all the online conversations you’re following in one convenient place, and informs you whenever something is added to a conversation.”
I’ve complained about blogging being broken before, and cocomment really helps overcome the conversation problem. Because they’ve made an extension that integrates with Firefox, they’ve effectively idiot-proofed the service, i.e. if I try to post a comment on a blog, the extension asks if I want to start tracking that conversation.
Just another slick piece of code that makes life easer.
