We have to move the Web from a feudal society to a free market. To do that we need a some platforms and micropayments systems that work across borders to unify identity, social networking and commerce. Otherwise Facebook, Amazon et al will do it!
Here are some ideas:

Note: the token described there is optional to the system, but without a native micropayment system we have to bolt on various payment solutions like Patreon or live with ad-supported platforms. The original Xanadu vision was hypermedia with micropayments.
I wanted to mention an interesting bit of engineering outside the pure programming space. It is not enough to design the web-based payment system, but we must take regulations into account as well. In order not to be encumbered with securities laws, the token must be designed in such a way that no one rational would purchase it for speculative purposes. In Switzerland, there is a FINMA legal framework for classifying tokens as securities or not. In the US, this is achieved by fitting within no-action letters of the SEC:

In short, a lot goes into a system like this, and it has to be in place to allow a free market by small entities able to compete with feudal lords. (Open source is a free market with a huge gift economy, ie many things are produced without a profit motive.)
Remember AOL, CompuServe, MSN? That was a Feudal society. You had to have AOL keyword Facebook, Amazon etc. The Web browser and HTTP invented by Tim Berners-Lee is what disrupted those centralized networks so you could simply use DNS and build on your own domain. Now you could have Facebook.com, Amazon.com and that is how they were even able to get their start. Do you think AOL would have allowed “keyword GMail” as an alternative email?
