I physically can’t use a browser without Vimium anymore.

Super Smash Bros (every incarnation). Never got the hype

Mastodon around four years ago. Couldn’t get into it then (or again more recently when Twitter really started disintegrating), and I think it’s because Twitter-style microblogging just feels conceptually broken for me.

Lemmy solves all the problems I had with both Reddit and Mastodon- just need to spread the word for the next couple of months and hit some kind of critical mass with adoption.
