Flocking to Flock?

Heard about Flock, the New Kid on the Browser Block via the Greasemonkey mailing list. I have read a few months ago about Bart Decrem starting a new venture called Round Two to develop Improved Firefox. It seems Round Two has become Flock now.

Flock home page says:

Flock has landed.

We're introducing the world's most innovative social browsing experience. We call it the two-way web.

Over the next few weeks, we'll be seeding invites to a few lucky folks.

On the face of it, it looks like Firefox bundled a bunch of popular extensions. The site is a bit skimpy on details and the extensions page lists the bundled extensions. How this is different from vanilla Firefox + the listed extensions remains to be seen. If all they are offering is the convenience of bundled extensions, it really doesn't appeal to me. But there's that mysterious two-way web thingy!

I am gonna reserve my judgement on this, until I play with it. Given that it is going to be available by invite only, it's gonna take some time, I guess.
