I’ve limited my domain purchases in recent years, and even let some of my bought-on-a-whim domains go (wordplumbr.com) after years of paying for renewals without using them.
But I still went ahead with the purchase of pencoyd.app when Google opened up that new TLD.
No specific plans for the new domain, so for now, I’ll link it to this post. I’ll leave the other 1,500+ possibilities alone.
