Everyone is focused on YaCy as a search engine for -discovery- and how it does or does not succeed at this early stage.
I think this looks fascinating as a tool for -memory-, I'd love to have it index every page I'VE read.
I very frequently waste time going -back- to google for some fact or thing I've already read.
This could be really killer for my personal use in this sense.
I could also see doing more interesting stuff with search that -your immediate peers- have read. Working peers that share your goals and interests. What pages come up for searches of things my workgroup has read? Perhaps integrate this with some active hash tagging and active process that people using the system together use.
Cool project, I think the cynicism about it is sad.
