Amazon Affiliate Blog

I have just spotted this blog today - http://affiliate-blog.amazon.co.uk/
An official amazon blog. Potentially quite useful (atm reading how 13 digit ISBN numbers will affect linking to amazon - if you have a book site that links to amazon you need to read this - http://affiliate-blog.amazon.co.uk/2006/12/13digitisbn_how.html
All those who use feed readers the blog rdf file is here

Also a point of interest with the amazon astores. I have just noticed that they link back to the associates program using the affiliate tracking id of this store. I must ask the question then - will affiliates start getting referral bonuses for referring new affiliates to the amazon associates scheme?
