More than anything, Facebook seems to have turned into a trigger-happy platform where people can quickly express their emotional state of being in exchange for some comments and likes.
There doesn't seem to be any 'protein' to the platform in terms of everyone using the platform equally. Should you comment something wrong, or something that the other person doesn't agree with -- all hell breaks loose because people want to have their voices heard.
Maybe that's just my opinion. Messenger as an app is definitely still useful and comes in handy to talk with close friends and family when away from them physically.
I am sure that some Groups generate decent content, specifically for sales, and crafty subjects, but business pages look more like billboards where a company changes their advertising message every other day. There's no sustenance to content, which makes the platform mindlessly boring.
