I have made a tweet in the past. It was not about typing long text, just want to share a Screenshot with friends and it's so annoying ti get images off the ps4. So making a fast tweet and send them a link was the most lazy option that came to my mind.
It wasn’t about really about tweets and more about being able to post screenshots and clips directly. I believe it also supports youtube and twitch or whatever
I think it was used as a discord workaround (at least for chat, not voice) as well as a way to do picture in picture of YouTube or other streaming services so you could multitask.
