Its true that some of my sites have recently been boosted last week according to some new algorithm change, such as the blog I was thinking about pulling out of the sandbox that ha21s#8%26n7;t ranked in a year now. That site is currently #5 all of a sudden.But, I was already noting changes in my sites well before that thread or that trend was even noted. See dated on the 22nd of October. And the site I was originally talking about in that comment that went from 31 to #13 in 9 hours, today is ranking at #10. So I am not sure if it went from 13 to 10 due to the new algorithm change or from the on-page SEO that was implemented on the main page.
