The great failure of the Internet is that the tools to make your personal home on it never evolved.

Think about it. When you create an account on something like Facebook, you automatically get your own space where you can post and follow people. There is no reason for personal web sites not to have played that central role instead.

But the tools to set up a web site never got easy enough for regular people to use. And we invented RSS to follow other web sites, but that never evolved to be bidirectional and interactive.
