Domains are cheap, shop around and get the cheapest 1st level you find, and buy a second level under that one.
For example, mylemmy.eu since .eu are by far the cheapest I can buy over here. It can go from 1 buck to 20 Buck per year, even more for special 1st levels (like .love)

Having said that, I will shut up but still think that notepad never needed a rehaul.
