Which got watered down by doubling it, adding pictures/clips and threads.

Today people write whole articles in tweet threads. It's terrible.

I agree that threads run counter to the point of Twitter, but I am grateful that they incorporated them. The users started making threads, and it used to be REALLY bad to read through them (being reversed and all). Despite this, everyone still did them, and everyone also always complained they were so hard to read.

If your userbase demands a feature so strongly it makes sense to incorporate it!
