From Search Engine Land: "No matter that it’s late Friday night on the start of a three-day holiday weekend in the U.S., Google has just pushed out the first update to its recent webspam-fighting Penguin algorithm. Let’s call it Penguin 1.1.
Google’s Matt Cutts announced the news a short time ago on Twitter, calling it a “data refresh” that impacts less than one-tenth of a percent of English-language searches.
Minor weather report: We pushed 1st Penguin algo data refresh an hour ago.
Affects <0.1% of English searches. Context: goo.gl/4f7Pq
