It feels like this is how social media and the Internet should have been all along. Truly run for the interest and good of humanity, and out of the hands of corporate control and profiteering. People, out of their own generosity and goodwill, host their own instances and let others use it for free. It's such an awesome example of humans helping each other and working to create abundance for everyone to enjoy.
I believe that everyone putting their time, money, and effort into building up the Fediverse - the developers, server owners, mods, and everyone else who keeps it alive and interesting - is helping to make the Internet (and by extension, the world) a better place. You all are awesome. Keep up the amazing work.
Also hi, I'm new here. I found out about Lemmy today, and I was so intrigued that I spent all day learning about it lol.
The answer is you don't tell people. We don't need to identify ourselves with a cheesy nickname.
