I suggest you read it. It's very interesting. When most people (okay, all people) talk about "the Google dance," they're referring to starting a new website, doing all the things necessary to position it well for the search engines (the gurus call it "SEO"), and then watching your brand-new website hit the first page of Google.
Only to fall to page 9,287 in the SERPs (Search Engine Results Pages) when the Big G figures out where your website should be.
Then it may rise and fall again a few times before settling in where it really is going to stay (until you do another round of SEO).
This is "the Google dance." Read wiggy's take on how he just had a dance with google and it was the opposite of the typical google dance.
