@xj9 I don't see the context, but I like #'s peer-to-peer search, despite their search algorithm not being anywhere close to # in the quality of results (probably close to #, though). I have hosted YaCy instances in the past, in part to help improve the peer network's results by crawling and indexing sites related to databases, Java, Tcl, Python, PHP (the things I was searching for most often at the time).

I intend to host YaCy again (perhaps feeding a # instance, so its results would not be wholly dependent on the goodwill of big corporate search engines).
