Firstly, I did try and solve the block size problem. Myself and Gavin did Bitcoin XT. It resulted in large DDoS attacks that took out entire regional areas because they contained a single XT node, any mention of XT being banned from the Bitcoin forums, large companies like Coinbase being banned too for simply experimenting with it, and so on. Miners also refused to run it because they were told that this would be democracy, and democracy was dangerous (they were almost all in China, so no surprises there). There was a large, organised and extremely hostile effort to ensure that the solutions we proposed could not be adopted even by those who wanted to. I did a lot more than just write articles.

As for this article, it says there's a second part coming where I propose concrete solutions.

Sure thing. If you know exactly what you need and design for that, than the outcome is allways better, than just randomly adding things here and there. So yes, a newly designed web would be something awesome. The thing is just, that it is somewhat complicated to design such a thing in the first place. And then build it. And while you build it, you discover many new things that also absolutely have to go into the design, so you redesign, ...

So in other words, I am curious for his thoughts on a new design and I would welcome it, if it leads to anything. I am just very sceptical, that there is something really awesome and concrete behind it. Vague ideas how to improve things, are allready floating around since the beginning.
