Is it worth switching to a new browser? Marc Andreessen never had to force users to ask that question when he built Mosaic in 1993. For most early adopters, it was their first browser.
But now he's backing the development of another browser, RockMelt. This browser is not perfect, but it does show that there's room yet in the market. If Facebook built a browser, it would probably look a lot like this.
This has been tried before. The other social Web browser, Flock, integrates Facebook features. Also, like Flock (at least the new 3.0 version), RockMelt is built from Chromium, the same Google-developed open toolkit underneath the Chrome browser.
RockMelt is solid effort and is worth trying. Here are some reasons you will probably like it; and, to be fair, some things that may turn you off:
Why you'll like it
It's a real social browser RockMelt shows which of your friends are online on Facebook, right in your browser. If you want to share something from the Web, you'll know who's going to see it right away. It makes sharing links and pages more engaging than using Twitter or even Facebook's site. (Downside: you can't scroll the left-hand "Facebar," which is sorted alphabetically, so unless you filter your friends by your RockMelt favorites, you'll always see your "A" friends on your list but you may never see your "Zs.")
