What kind of thoughts domainer111 . . . is it your name ?
I think it's a nice one with good development potential. There's a lot of books about science out there . . . Amazon affiliate program should make for a quick and easy development and then the possibilities to branch out in to more niche stuff like scientific journals or textbooks etc. Seems a reasonable price at $1k to me, but then again I was involved in picking some of these so I'm a bit biased
Looking at its history and the need for high traffic to make money on a low margin item like a book, not to mention that science books are niche, I would say $500 would be about right.
Yeah, it's killing me that I'm not able to bid on this domain, I would LOVE to build a business around that site. Just too dang broke for my own good. JMO but I bet it goes really high.
