I took your idea really to heart and so I built this unique website called
http://www.anysubjects.com which is I believe the first website designed to provide the world with hundreds of Kindle ready links.
I set myself the challenge of finding as many websites as I could which I could use on my Kindle browser. The restriction I set myself was only websites which did not need me to change any of the settings on the Kindle such as the font or screen orientation could be included.
I have listed hundreds of sites, far more than my Kindle bookmarks could hold. The idea being people bookmark this site and then work from there. Any websites I have missed, they are free to tell me, and I will add it in so that everyone sees all their favourite Kindle ready websites in one place.
I hope other people like my efforts!
