Web 2.0 - Flock, the social web browser

I'm quite happy with my latest "discovery" (but I'm also wondering if things are starting to get out of hands)

A social web browser?! Sounds exciting!

As described on the site: "Flock is a free web browser that makes it easy to connect with your friends and express yourself online"

I haven't tested fully, so I'll give my experience feedback later.
In the meantime, you can download your Flock browser here.
