Hate getting or giving the “K” reply but don’t have a wordier response? You might warm up to the Like button now integrated in the mobile versions of Facebook. If you take a look at your Facebook iOS and Android apps, you’ll see that one-tap thumbs up button that replaces the Send button when you haven’t typed anything in yet.
It’ll be interesting to see if this feature catches on. Sadly, if you’re using the desktop version, you won’t be able to get in on the liking action.
