100% right :plus they keep expanding there sites in big money terms with success.

You can build a small travel site that can rank at #1-#3 for 1 keyword (place name)and even rank over wikicr$%^p)
You just need a few quality links from extremely relative sites and of cource more then 1000 words for every page with original content ,a few outbound one way links to other sites with relative content that will help your audience and there you are.
Sites that I've made a year ago rank since last January at the top.Certainly looks like my formula works and sandbox applies only to sites that trigger a red light.
