Thanks for the review on Presearch, I've been looking into BitClave but looks like I will have another to look into as well.
While I find a decentralized search engine quite scary in the short term (I have many sites making money through Google, Amazon, etc.) I do think it's best for the long term but just don't see it happening any time soon. I'm also not yet convinced on how they will pull it off, every way I look at it, the algorithm they use can and will be manipulated in some way but we can always hope it works out!
I agree, but the really scary part is when a search result can't be delisted because it's become a permanent part of the block chain. Now think about revenge porn for a moment.... I hope they know what they are doing. Greetings!
