Social network Sir?

Social browsing toolbar
Do you socially network, (as in the on-line sort and not down the pub)? We’ve just stumbled across this little add on (Me.dium (http://www.me.dium.com) Described as ‘Real Time Social Search’, essentially, it lets you browse online ‘what is hot right now’ and to influence what should be featured in said hot zone. You can also chat, share music files and videos, and see what your friends are looking at at the same time (once installed, a small toolbar appears in your browser window, the top panel of the sidebar is a map that lets you view what sites your friends are visiting, you can view your friend’s profiles and also send them a message similar to Facebook).
You can specify your visibility settings, ie: how much people can see without being approved by yourself. I read that the application is secure and that the program suspends sharing when you leave the site.
It all rings a bit ‘cool, happening and right now’; a quote from the site: ‘we tend to surface news, reviews, pictures and videos that are hot, right now, according to crowds of people just like you’.
