Honestly, this is a pretty clear case where federation should win out. I answered someone above, but governments using a private service like twitter for actual public announcements imo is broken. I hope that Mastodon and federated services take off and turn into a turnkey style service somewhere. Like, setting up your own Mastodon (or Lemmy!) instance I hope turns into something just about as easy as setting up an email account.
With Twitter's dwindling user base and each, people should just jump ship and migrate to mastodon. It's honestly what Twitter used to be and better than everything Twitter is now nor what musk has turned Twitter into.
I wasn't a heavy poster on Twitter, but I was a heavy user. Unlike the Lemmy/Reddit model, it's much more real time. So when I wanted to see how things were going with a piece of news of any sort, basically, twitter was better at that.
Its also much more person centered - you curate specifically a list of who you want to follow rather than just topics, so there could often be crossover. Usually for me, this meant I'd listen to some podcast or something for a while, figure out I like the host and their personality or often just taste, and then follow them. The added benefit being that most people I'd follow on twitter weren't so big that if you tweet at them and you're not an asshole, you'll get a response.
It would be a godsend if there was a way to block certain results from search engines. I do not want to have want to have any more Twitter links or reddit links propagating my results. I don't even care if I miss out on some vital piece of information to my query. I just don't want those sites in my search results.
