Even though I don't use Twitter much any more, I fully agree here. Whenever I see the "[thread emoji] 1/?" I'm already done.
I can't even fathom why anyone would put the energy in these "thread" style tweets. Twitter content will forever remain fundamentally ephemeral: it's hard to find my own tweets from years back, let alone someone else's I found insightful.
The normal tweet format works well for ephemera, it's a medium for shower thoughts and sloganeering. Similar to how a typical child's sand shovel is correct tool for building sandcastles. Twitter threads feel like someone is handing out full sized shovels for work you know will be lost for ever when the next tide comes in.
