Some years ago I appreciated the character limit of Twitter because people have to be creative and to the point to express themselves, but with the years I start to thinking that this limitation was also a curse for communication overall on the platform.
I don't log in, so I can't read the comments, but it also is sorely missed that I can't see people reply to specific ideas or comments. It's all just a soupy unstructured mess.
We already had blogs. Why we'd take a medium built for interaction & turn it into a place for long winded things that should be articles or blogs doesn't make sense to me.
I would say the popularity of Twitter and its 140 character limit were a curse for communication fullstop. Globally, and irreversibly.
Facebook gets a lot of flak for being an echo chamber with targetted ads and disinformation, but Twitter never got the same level of critique in damaging online discourse.
Twitter specifically required people for a long time not to have long well-thought out ideas - but require hot takes and nothing else. Every political, social or economic position that was discussed had to be distilled to 140 characters - this effectively scrubbed nuance from any position. Along with retweets, this meant that all news, and all online discourse was reduced to "the hottest takes" without any level of complex thought.
I think they doubled it to 280 forever ago anyway.
