When I first got on Lemmy I signed up for a small instance my friend was on. Mostly ended up lurking. Before ditching that account, because I forgot the password, and was looking to go to a different instance anyway, I looked up what instances had the most federations. world had a lot, and no hexbear. It also has a old style interface, and blocks NSFW content, so I can more safely browse in public/at work. So I switched to it with my main and then separately logged into places with open NSFW content.
