Flock, Time for Another Browser?

Anyone heard of Flock? The new social browser using the Firefox engine. It's designed specifically for that aspect of the web and is uniquely more intriguing than Firefox. It has a built in function of sharing and uploading photos using either Flickr (Yahoo) service or Kodak's photo gallery, posting on a Blog, and all the current capabilities and extensions for Firefox. The downside? It will eat more CPU than Firefox due to the built in capabilities.

The question here is, "Will this be the future of Firefox, Social Web Browsing?" There will be lots of people who will use Firefox to Work and not play, but then again it's only logical that Firefox will evolve into a social web browser, and should it choose to do so, there will be a large crowd that will follow. What's your take?
