Flock is actually built on the Firefox core, but aside from a familiar menu structure I think the similarities end there. Exhibiting their mantra of building a better tool for the web, Flock has social bookmarking, blogging and even Flickr tools built right in. The first time you star (bookmark) a site, Flock asks if you’d like to enter your del.icio.us account information, in which case it will integrate with your del.icio.us bookmarks for any sites you star and tag from here on out. A great idea that, in my opinion, just about every browser should’ve done the day del.icio.us debuted. Keep reading after the bump, as this browser has some more great tricks up its sleeve.
