back of a spreadsheet; back of the net

I’ve recently bought a Kindle and so has my Mum. In an attempt to reduce both my waistline and my monthly expenditure on lunch I’ve started eating soup in the canteen and using the saved money to buy ebooks.  On a number of occasions I’ve logged on to Amazon and been overwhelmed by the choice. Overwhelmed to the point of paralysis.  I’ve gone to the shop with an open wallet then walked out without spending any money.

I want a system that combines knowledge about my tastes with better meta-data about books on offer and a reputation management system for reviews and reviewers.

Here are some suggestions for Amazon about how they could help me spend money.
