@smokey That's all true on paper, but it doesn't mean people view it that way, especially given Twitter's real-time nature.
Young people treat Twitter like ephemera. It is the scratchpad you reach for in an impulse when you want to share thoughts about something that is happening right now. Yes, that record is permanent, but no one actually considers it to be so, nor does anyone really expect people will go back through their archive to find dumb things they said in the past. Just ask politicians. While the UI is very similar visually to what we have here on Micro.blog and the underlying API calls are about the same, the mental model is completely different.
It is much harder to be impulsive on Micro.blog because you always feel like you are being watched. Ostensibly someone has to be reading every post to decide what goes on the Discover page, and you would feel bad for them if they had to read the 100-something posts you made during a e-sports game they didn't even watch. I'm pretty sure this is by design to encourage thoughtfulness in your posts, but it does feel incredibly weird and constraining to someone coming from the other side. I make less posts here than I do on Twitter but they tend to be more thought out and with better capitalization and punctuation. That said, I do feel like they read as "less authentic" by trying to fit in to the mold of what people expect posts to look like here rather than just posting the same stuff I tweet on Twitter.
(The weirdest thing about all of this is that the main issue with Twitter and third-party clients right now revolves around the deprecation of the streaming API which is what enables stream-of-consciousness tweeting to be viable in the first place. Twitter was the last big social network with a straightforward reverse chronological timeline, and they signed deals with major sports leagues to be the streaming partner for those games, and yet... they've dumped the chronological timeline for an algorithmic one, they never integrated streaming into their own mobile clients, they never made a play around integrating live tweets into their live programming, and they're deprecating the one strength they had over everyone else: their real-time nature. It makes no sense whatsoever to me.)
