I actually worked on the spurl search engine once upon a time... but that was a while ago! I haven't heard that name in a long time.  It was a great service, but at the time there was quite a bit of saturation in the web-based bookmarking market. Furl looked like the clear leader, at the time, but in the end I guess it was del.icio.us with its simplicity coupled with social underpinnings. Pinboard has emphasized the former, focusing on raw, simple utility.  I think it is here to stay -- they seem to know what they're doing, on a technical level but as always, in the long run, we'll see.

Great shit.

From that list, I'm reading The Windup Girl now. It's pretty good.

A Canticle for Leibowitz is one of my all time favorite books. There's also a sequel, but he doesn't appear to have read that.

Recently I read the series "The Entire and the Rose" which I really enjoyed.  Martha Atwood's "Oryx & Crake" and "Year of the Flood" is a pair of dystopian books that might be my favorite story right now. For relatively hard Sci-Fi, Sean Williams' Astropolis series is incredible in scope.
