In staying the course to become more social by way of integrated ventures into existing social networks, Mahalo's Follow feature has added support for StumbleUpon and Facebook. Mahalo Follow already had support for Twitter, Jaiku, Google Bookmarks, Del.icio.us and Magnolia. The new additions of StumbleUpon and Facebook are not surprising, and given the nature of Mahalo Follow, they've been a long time coming, especially for Facebook integration. Now you can send search result items directly to your Facebook mini feed, for all your friends to see.
