I found AZ ratings to be mostly useless, what would be better is the total number HN/SO points accumulated from all the recommendations for that book.

edit: not a mix, but separate points for each community

Mmm - a kind of book karma. Something like mixing the karma of the commenter with the heatness of the discussion etc ?

I think being able to filter on SO vs HN would definitely give different results, too.

The topics are sometimes fairly different on both sites.
