I think what people are really looking for is some kind of software platform that allows them to put up their own website, so nobody else can delete it out from under them, but also have some kind of interaction with other people with their own independent sites.
So that they can press a button and "retweet" something someone else said, or reply to it without creating a new account on the site of everybody you want to reply to etc.
The hard problem is probably to get some kind of a distributed user accounts database, so that you own your account based on cryptography rather than the capricious whims of billionaires, but still use it on more than your own website. Maybe something like Namecoin but for usernames.

I seriously think that solving decentralized identity (and trust) is the most important current goal in the field of online technology. Once it is solved, all future innovations become ten times easier to implement and adopt. That's probably an exaggeration, but it could certainly be a more foundational technology than cryptocurrency, for example.
Anyway, to get a sense of the state of the art, I recommend this paper[0] from late last year. To pick just one of the approaches discussed in it, let me mention BrightID which is documented here[1].
You're describing the indieweb: your identity is decentralized and is your domain name (not at the whims of billionaires), you put up whatever content you want but typically articles, interact with other people's content (likes, retweet, comment) without the need to create an account anywhere.
The real blocker is that in practice there is a huge step between creating an account on a commercial service and buying your domain name, setting up a website and making it reachable to the world.
