I recently purchased a domain for myself as a why-the-fuck-not purchase and I need some ideas for what to put on there. Some ideas so far include:
Small Blog
Personal S/FTP server to sync back to
Minecraft server
I use mine for a VPS running Ubuntu. It let's me mess around with stuff and also let's me host things like discord bots without needing a local pc always running.
My VPS is pretty cheap, something like 10 bucks a month so it's worth it for me.
