Yeah I gave it a look. It is really light on details. I think you have to be clear why this is better than Ethereum, the fact that web browsers are nodes and are mining isn't really a feature. Having every node mine isn't very useful either, it is unlikely to increase the security of the network and has follow on effects for memory and cpu utilization for end users.

Anyway, I'll look forward to hearing more about it, but given the high barrier to writing a secure, scalable blockchain I'm reserving judgement until there is enough information to do a more formal analysis.
