I think that I would like a more personal version of digg.
For instance, over the years, I have tagged (by sending the links as emails to my friends) several xkcd strips as “Like”. But there is no way for me to grab just the “liked” strips, other than with bookmarks (a very messy way to store this information).
There should be a web front-end so that I can surf a given website, but only see the links (or search filters, or whatever) on it that I’ve tagged in the past.
It goes back to my idea of a 3D lattice of web searches, that was obviated (at the time) by tabbed browsing.
But there’s still more to it. I would like to go back to that search I was doing 6 months ago, and remember where I was at the time.
hm.
