Time has run out for the Flock browser, as support for the innovative social networking web client will be discontinued as of April 26. "we encourage all Flock users to upgrade to one of the two browsers listed below (Chrome or Firefox). Both are based on the same reliable technologies as Flock, and both are being actively maintained and improved. Also, each of the following browsers has a broad selection of add-ons and extensions to customize and extend their capabilities." I wonder what this means for the future of Rockmelt, which just released Beta 2.
