Well, it looks like those "meaningful updates" Twitter talked about last month are finally here. Looking at the changes Twitter has made, I think it is a stretch to call muting pre-selected keywords "meaningful updates" but at least it's something. Now, users will be able to mute seeing certain words in their notifications, such as racial slurs and curse words -- an update that was in the works for many months. People can also block whole conversations. The change may help lessen the ability of abusers to reach their victims, decreasing their motivation to do it.
