Yet another web browser - but this one is kinda interesting...

Flock - The Social Web Browser

Why it's interesting:
It integrates many aspects of your social web presence into the browser.  For example, there are widgets built into the browser to manage a myriad of your accounts, including Facebook, MySpace, Twitter, GMail, Yahoo! Mail, Blogger, etc.  In fact, I'm using the blog post feature of the browser to create this very post.

Other points of note:
It is based on Firefox, and has a somewhat similar feel...sorta.

Will it become my new default web browser?  Highly doubtful.  But it's still pretty neat.  Perhaps the new order of preference will be:
Firefox
Chrome
Flock
Opera
Internet Explorer
