Today is a sad day, being that Google has not refreshed the Penguin algorithm for a year. Today, October 4th, is the year anniversary of Penguin 2.1 - those hit a year ago, are probably out of business by now.
Today is also Yom Kippur, well, it just ended for me an hour or so ago.
We know Penguin 3.0 is coming really soon but a little too late, don't you think? If I had to put money on it, since Google has released many updates on days where I am offline completely for Jewish holidays, I bet it will be released this coming Thursday or Friday, which is Sukkot.
Anyway, to brush up, see our massive Penguin section.
