Say goodbye to favs. The Twitter stars you've so desperately collected over the years with your witty status updates are being replaced with hearts. Starting today, both Twitter and Vine will start transitioning to "likes." According to Akarshan Kumar, Twitter product manager, stars could be confusing to new users, "you might like a lot of things, but not everything can be your favorite." The social network has been testing hearts since June and says that those people love it and that the heart symbol transcends languages and cultures.
