You can buy blue checks, I guess. On the other hand they shut off embeds and access to replies unless you were signed in so it's functionally dead as a "website". Oh and sometimes there's child porn? So I guess it was overkill unless you care about things like moderation and safety. Anyway, excited to see how it very fairly handles the next US elections! I'm sure most of the remaining devs have invested their time there.

no, but they weren’t exactly churning out new features in the 2010s either

Not really the point. I think Musk just wanted to trim headcount down to something that could keep the product running, more or less, and get rid of all the costs he could. He didn't care about turning Twitter into a hugely successful business or an amazing product. He just wanted to be able to control and influence what people say on the platform, and push his agenda and politics.

Creator monetization, which is great.

In general though I feel like the less new features it adds, the better.
