Gravatar has been a thing since 2007.

Yes, and I have been using it since then, this is quite something else tho.

> this is quite something else

In what way, specifically?

From your original comment: "imagine something like steam profile avatars/pictures etc. tied to your identity that you can use on any page that implements it."

That sounds 100% like Gravatar. We already have exactly that, without any of the problematic aspects of being tied to NFTs or blockchain.

I assume you never used steam in the last years? Games drop avatars as items for steam inventory, and you can trade them and put them in special slots, they aren't just random images, its not just avatars its also frames of avatars, slots of stuff to show on profile, animated backgrounds etc.

Except trading of Gravatars, right?
