As a user, I want to browse all sites that have annotations

[toppsdown]

Hey guys, just learned about this project and I'm very excited by it. One thing I would like as a user is to be able to find websites that are annotated. As a secondary feature, I feel that the value of annotation is correlated to the density of conversation, so I would like a map as to where conversations are taking place; perhaps a heatmap or a ranking system of conversation activity.

Thanks!
