Facebook’s Like button, one of the most often used features that allows the site to profile your interests, has began popping up on external sites (Geek.com for example). Meanwhile, Facebook is taking the Like button to new places on their own site as well. It always bothered me that I couldn’t like someone’s comment on a News Feed post. The lack of such a capability has led many people to credit commenters in their own comments, adding to the overall noise.
This has come to an end, Facebook wrote in a Wednesday blog post announcing the new comments liking feature. The Like button and the ability to comment on News Feed stories go together like “peanut butter and jelly,” said Facebook’s software engineer Tom Whitnah. Don’t freak out if you don’t see the small Like button underneath the comments because Facebook is rolling out the feature gradually.
Facebook has to implement new rules for Facebook Live because people are literally the worst. Now, if you break the rules you'll receive a ban.
