I guess it all depens how the new tokens are generated. If we look at Steem it really is the power of the brain.
But if such thing will be spread on regular website they may step into the pitfall that tokens have to be bought or take people can only award a site with token, when they are also listed on the particular block chain.
Or some kind of overlay has to be used to browse the websites in. A competitor of Mozilla, Internet Explorer and so on.
Now I'm writing this down, I'm thinking that this really could be a great idea! Still lots of challenges ahead!
