Welcome to WebmasterWorld Guest from 220.127.116.11
Earlier this week Google launched an algorithmic change that will tend to rank scraper sites or sites with less original content lower. The net effect is that searchers are more likely to see the sites that wrote the original content. An example would be that stackoverflow.com will tend to rank higher than sites that just reuse stackoverflow.com's content. Note that the algorithmic change isn't specific to stackoverflow.com though.
I know a few people here on HN had mentioned specific queries like [pass json body to spring mvc] or [aws s3 emr pig], and those look better to me now. I know that the people here all have their favorite programming-related query, so I wanted to ask if anyone notices a search where a site like efreedom ranks higher than SO now? Most of the searches I tried looked like they were returning SO at the appropriate times/slots now.
I just wanted to give a quick update on one thing I mentioned in my search engine spam post.
My post mentioned that “we’re evaluating multiple changes that should help drive spam levels even lower, including one change that primarily affects sites that copy others’ content and sites with low levels of original content.” That change was approved at our weekly quality launch meeting last Thursday and launched earlier this week.
This was a pretty targeted launch: slightly over 2% of queries change in some way, but less than half a percent of search results change enough that someone might really notice. The net effect is that searchers are more likely to see the sites that wrote the original content rather than a site that scraped or copied the original site’s content.

One useful change Google could do is to make wikipedia a result you must ASK for.
could someone please develop a browser extension / ad blocker to cut off wikipedia and repressive government sponsored website results in G or at least tank them to position 10,000?
For now, I can say from serp watching that a lot of search refinements that I've been seeing on various searches, like multiple pages returned for a domain, etc, seem to have shifted with this update...
