Twitter is changing the “fav” star to a “like” heart, and I don’t like that. Neither does Dave Winer:
You may have Favorited something about a terrorist group, but would you have clicked on a red heart? At the very least that’s going to take some getting used to.
No surprise that third-party clients will be required to obey the new terminology and symbolism. Welcome to the new Twitter; same as the old Twitter.
