I'm trying out Flock, a cross-platform browser based on Firefox that adds social networking, photo, RSS and blogging features.

It's pretty slick, but it's definitely not ready for prime-time yet. It crashed on me navigating through some of my RSS feeds, and the UI, while excellent so far, still needs polish and performance tuning.

Flock has offices in Silicon Valley and Victoria, BC (where I live). I've seen people around town wearing Flock T-shirts, I assume they work there. :-)
