This new extension for Firefox users seems to me like it could be the next big thing in social browsing. Upon installing this extension, you can open a small messenger type window at the bottom of your screen, where you can chat with other users who are on the same page.
This is a pretty new service, so there aren't that many people on many pages (google is always busy though), but as I mentioned before - I believe this one may make it big.

I'm giving tags a try. I'll see how I like them.
