I'm not thrilled about the Etsy thing either, but they posted about it and it doesn't sound as bad as some articles had said: http://www.etsy.com/storque/handmade-life/rethinking-feedback-12472/?utm_source=bronto&utm;_medium=email&utm;_term=Read+on&utm;_content=etsy_success_031511&utm;_campaign=etsy_success_031511

It affected about 25% of users, it wasn't an active change but a side effect of an outdated system, and they fixed it pretty quickly.
