Browser extension: A way to see discussion directly on sites, instead of having to search for the article on snapzu?

I saw this thread on HN and realised that there's already a community here, and this way you could see discussion that happened on snapzu instead of having to look for it, which is always slightly cumbersome and has a much higher threshold than just clicking on a plugin. A browser plugin with a sidebar or something might work. Alternatively, if there's no discussion, an option to redirect to submit, or directly in the plugin so that you might be able to browse the article/whatever to pull info out of while putting your snap together.

Thoughts?
