This site will not be updated due to lack of enthusiasm (on my part), so
I have passed on my data to Michael Talbot, who has made the data available
here .
From what I understand, he has not received many (if any) recent votes
(hence the lack of a recent update).
You could also check out
Alexlit.com which is apparently
being upgraded, and should be online again in early 2008. This was the best
personalised book recommendation site I have seen.
