Google is killing themselves. In case you have not noticed many of the SERRPS are not good. Today I did a search for "acronis true image". Acronis was not of the first page. In Bing they are number one. These daily changes in the code are finally catching up with them. Then there is the stupid stuff with all the ads, image search that shows other websites with adwords and doorway pages. http://www.seobook.com/google-doorway-pages
No one can kill Google except Google.
No one can kill Facebook except Facebook. Many people don't trust Facebook. That's a problem.
