I go by the name Blue, here on linarite.net and elsewhere.
I don't post often at all. But I do have some accounts for keeping in touch.
Yeah, this exists. I never see anyone on here, but here is my username anyways.
@linarite:feneas.org (I'm on the feneas.org homeserver.)
I prefer using Mastodon over Twitter, so you won't find me here very often. The only reason I have a Twitter account is so I can follow some people. The chances of me tweeting on there, or replying to people is slim.
My email is hosted on ProtonMail, so if you are using that service it should automatically encrypt to my address.
