I haven't seen much discussion of Google's Panda update on Hacker News. I'm sure many legitimate sites have been negatively affected. I wonder if people are hesitant to share their experiences here because they think that we'll judge their sites negatively <i>because</i> the algorithm changes judge their sites negatively.<p>I have a very legitimate site (<a href="http://onlineslangdictionary.com/" rel="nofollow">http://onlineslangdictionary.com/</a>) that lost 25% of its traffic due to Panda. I'm writing up more details and I'll post them soon.
