I just set up a YaCy instance myself last week after being inspired by your post on hackernews from ~7 months ago. Thanks for sharing that. I found some other helpful resources online for this too. I wrote about my configuration in case it might be helpful for anyone else who'd like yo play with YaCy for bookmarking. I haven't had it up long enough to know how useful it will be for me yet, but its been fun to play with. I also wrote an Android app to help me index specific pages from my mobile device with just a few taps.
