> To really control my data and my online persona.

But HOW does blockchain give you "control over your data" in a way that uniquely requires a blockchain? You can do a heck of a lot just with existing tools, like asymmetric crypto and hashing.

The only use I can think of right now is to globally prove that user X really did publish Y at some time Z in the past. In other words, preventing anyone from "backdating" a piece of content.

Now, while that may be useful, it's not really offering you more control over your public persona. It's really just restricting what everyone can do in order to curb a certain kind of abuse.
