Perhaps the world does not need another web browser -- but it may want Bart Decrem's.

Decrem and a small cadre of programmers in Palo Alto, California, have spent this summer quietly readying Flock, an open-source browser, for an early October beta launch. Several members of the team, including Decrem, hail from the Mozilla Foundation, which produced the Firefox browser upon which Flock is built.

Flock advertises itself as a "social browser," meaning that the application plays nicely with popular web services like Flicker, Technorati and del.icio.us. Flock also features widely compliant WYSIWYG, drag-and-drop blogging tools. The browser even promises to detect and authenticate all those user accounts automatically. It's a clear attempt to be the browser of choice for the Web 2.0 user.

The space shuttle Discovery roared into the skies over Florida Tuesday morning as NASA returned to manned space flight for the first time since the 2003 Columbia disaster.

The spacecraft lifted off as scheduled at 10:39 a.m. ET, following days of troubleshooting to fix a faulty fuel sensor in its external tank.
