Flock is a web browser that makes easy to use community activities on the internet like facebook, flickr and also it supports on viewing emails (on Gmail and yahoo) an many more. It is true that now the internet users are using more functionality on internet 2; so it supports most of them.
Flock itself says it as a "social web browser" so I downloaded it and used for a couple of days. The main thing on Flock web browser is you can download to for free. It seems very easy to use facebook through Flock and also it is pretty easy to use flickr (image share on yahoo).
