This is one of the most interesting part of the whole post for me:

Through intense digging I found a researcher who left a notebook public including tweet counts from many years of Twitter’s 10% sampled “Decahose” API and discovered the surprising fact that tweet rate today is around the same as or lower than 2013! Tweet rate peaked in 2014 and then declined before reaching new peaks in the pandemic. Elon recently tweeted the same 500M/day number which matches the Decahose notebook and 2013 blog post, so this seems to be true! Twitter’s active users grew the whole time so I think this reflects a shift from a “posting about your life to your friends” platform to an algorithmic content-consumption platform.

So, the number of writes has been the same for a good long while.
