Lots of people were confused about the purpose or utility of 'micro-blogging.' It only really clicked for people once you had minor celebrities using the platform to crowd-source information, advice, and ideas from fans.
Also you can think of Twitter as a standalone spinoff of Facebook status updates user behaviour but with hashtags. I actually find Twitter more compelling than Facebook but somehow Twitter's management was able to ruin Twitter. Now we have not only Twitter but X, Threads, Bluesky and Mastadon. It is way too fragmented but imo they should all interop and work as an one ecosystem.
