A single domain helps so much, regardless of what you have planned. I basically use mine just as bookmarks. There's a dedicated subdomain for dynamic DNS. I make use of SRV records. Costs me like 6 bucks a year. You don't need huge ambitions or dreams for a domain name to make sense.
It’s just a joke reference to some people who hold onto a domain specifically for their pet project that they aren’t actively pursuing. I’m sure it doesn’t apply to everyone
We're really consuming them at an alarming rate. Soon, the only affordable ones will have either 20+ characters, a sus TLD, or just be a nonsensical string nobody can pronounce.
I got three so far. Bought my first one as motivational commitment for a project, then came the second... And the third... And it'd be cool if I had a fourth one...
