I've never used Twitter, nor liked it, but in 2010 I had to observe that it was indeed useful when it became one of the primary ways for people to communicate during the Arab Spring.

Since then I kept not being into it, but at least I thought it had some important value I had not seen.

Now it's all locked up, so it really has become useless (and I haven't even talked about the rampant disinformation)

RIP Twitter
