Senh: I've already been seeing some of that in action. I've noticed that the results I get when I'm logged-in are different from the results I get when I'm not. Sometimes, I get results from sites that I'm Plus One-ed on. Sometimes I get results from sites that I visit often, like MoviesWithButter.com, for instance.
Senh: Interesting that the one site that Google supposedly targeted with their previous algorithm has almost no effect on the site's traffic.
Senh: No wonder. Traffic to my site dropped by 30% from Wednesday to Thursday. The example used in the article from eHow is borderline, but here's a better example: http://ezinearticles.com/?Why-Social-Media-Optimization-Needs-to-Be-Done&id=5720775. There's absolutely nothing useful from that article. All it does is mention the keywords "social media optimization" a bunch of times. There aren't tips on how to do the optimization. There's no even a real discription of what it is.
Senh: That's lame. So instead of developing a better search engine, they're just gonna copy Google's, and call it their own. Way to innovate, Microsoft.
