We just rolled out Mahalo Follow 3.0, and the big new feature this time around is the ability to cross-post any links you recommend to Mahalo via the Follow toolbar between Twitter, del.icio.us, and Ma.gnolia. Just add your account info (process shown below), and after recommending a link for a Mahalo search term, your link will be auto-posted to whichever services you set up via the service’s API.
Notice that you can choose which services to cross-post to each time you recommend a link.
Follow 3.0 is compatible with Firefox 1.5 through 3.0 Beta 2 and Flock 1.0.*, and you can install it at the Mahalo Follow homepage.
