A first look at the Flock social browser
One of the nice things about open source software is that it gives developers the ability to reuse and re-purpose code. Take, for example, the Flock Web browser, recently released as a pre-beta developer preview based on the Firefox code base. Flock sports a layout similar to Firefox, with a navigation toolbar, bookmark toolbar, a search tabbed interface, and so forth. But it has been dubbed a "social browser" because it integrates with weblogs, photo and bookmark sharing, and other "social" services on the Web.
Flock uses del.icio.us to manage "Favorites" so you can share bookmarks between computers, and make easy use of del.icio.us bookmarks in Flock.
