No two ways about it -- Amazon is the most useful link for most people. They've got the biggest market share, they have the most reviews by other people, they sell both print and ebooks. That's also why they have so much power. So do I withhold my minuscule contribution to their coffers and mindshare, when that might reduce the chance of someone thinking, "I'd like that!" and actually following through with a purchase?
Posting the reviews to Amazon is an easier decision. It does make a difference to sales when there are reviews, and I think on balance it does more good than harm to provide Amazon with that content.
But I think I need to make more of an effort to get Kobo links as well, where possible. They're ebook-only, but at least they use an open file format and eschew DRM unless it's requested by the publisher.
