good for them.. not so good for the rest of us.
i think Kifi was the only free service that it could do real search to the contents of bookmarks. In fact i had a fairly big kifi library for machine learning & stuff (<a href="https://www.kifi.com/gep-gep/machine-learning" rel="nofollow">https://www.kifi.com/gep-gep/machine-learning</a>) and after a while i stopped tagging because search was so good. For example if you searched for 'pca' it would return all the articles in your library mentioning principal component techniques regardless if the word pca was a bookmarked keyword, tag or in the article's title.
Does anyone know/use a similar personalized search bookmark engine??
