Hachyderm is my instance. It’s heavily influenced by techy people, but there’s a bit of everything there. Strong culture of safety for social justice - some of the most followed LGBTQ and Black accounts post from there. I’d highly recommend.

Others I’ve enjoyed browsing are indieweb.social and toot.community

Yes! I feel the same when I leave home without one of my pens. The Everyman was a great pen - I never got one, but I remember wanting one when I can across it on Huckberry.

It’s a luxury purchase, but Lamy makes several fountain pens that will last you the rest of your life. The Safari is a great entry pen, made of the same plastic as Legos. The 2000 is a gold nibbed pen whose design remains unchanged since 1966.
