I was already on Mastodon by just having a Vivaldi (the chromium browser) account, and it’s just lovely I’ve spent most of the day setting up lemmy, even though I joined feddit.dk 2 years ago, it’s only just now I’m taking it seriously.
And, while not related to the fediverse per se, I switched to linux a year ago.
The only service that’s hard to drop/switch away from is Youtube imo.
