It seems that from the start the point was to share novelty domains, i.e. letting other people make subdomains off your domain is the point, and the rest of it kind of grew out from there.

I've put a couple domains on there expressly for that purpose... they also support dyndns options which makes it nice for home server networks.

I do wish that Let's Encrypt would work with them to whitelist all the domains on freedns.
