Now, obviously, I would encourage anyone building something like this to be as transparent, accurate and authentic as possible. A high quality resource that lists a "best and brightest" in your niche - be they blogs, Twitter accounts, Facebook pages, individual posts, people, conferences or whatever else you can think to rank - is an excellent piece of content for earning traffic and becoming a known quantity in your field.
I love #22. Sometimes SEO companies say once you start blogging you will get all this traffic and grow your rankings, and with expectations like that it's hard after 8 months or so to keep blogging with minimal results. But I went back to SEOmoz's first posts and sure enough there were only 1 or 2 pageviews... Now look at this post alone with over 3000 tweets and hundreds of likes, comments and thumbs ups!
