For relatively recent arrivals:
Mastodon is pretty unfriendly to brand promotions, but in my experience very very friendly to "LOOK AT THIS NEAT THING I MADE!".
Do not hide your enthusiasm for your neat shit. If you have a habit of trying to imitate corporate-brand-style self promotion, maybe try to let it go. Talk personal.
(Prompted by @clarkvalentine posting and getting responded to similarly else-site, and going "Wait, it's been a minute, new people back home might not know".)

As we all know playing RPGs and collecting them are two similiar but unrelated hobbies and why would you deny people a little joy in their lives?
Also, I like to know what's going on. Sometimes I even tell other people about it.
