I've seen a articles and questions and forum posts that mention Panda but I've not seen anyone actually explain what exactly panda is. I've also noticed the term penguin a couple of times just not as often.
Once I start making $4 a day with my 2 hubpage profiles and my 20 blogs, Google comes out with PageRank updates that they codename things like 'Panda' and 'Penguin.' Then I'm down to 30 cents again.
You keep hearing about Panda and Penguin because they were important as Google is tossing out sites that are spammy, sites that buy or sell links, and a lot of other sites get penalized in the crossfire.
Hubpages was hit hard by the Panda update and I don't think ever fully recovered.
