I use Twitter for tech. I don't understand why people would use Mastodon for anything other than tribal political signalling purposes.
The UX of Mastodon is terrible compared to Twitter, in terms of global post search and discoverability of accounts.
And the arbitrary/political natural of fedi-blocking means I'm only seeing a subset of views on Mastodon.
I'm not saying Twitter is perfect, but I think the opposition to it seems contrived and coordinated.
