barrier to entry. You can start broadcasting your thoughts within seconds with no infrastructure.
No need to worry about hosting content until you're big enough to be censored.
You could even deterministically map pubkeys to handles with something like bip39. it won't be pretty but it will be unique, human-readable and uncensorable.

so it's subjective.
