It all depends how Google classifies you IMO, informational, forum, local, e-commerce
Spoke to a Google rep years ago who said start your site with unique content and build up. I doubt if anything's changed. At least we have confirmation that it's quality over quantity.
And quality now brings into play other metrics. Truly, I'm seeing large sites with less than 125 words of content on a page, but stunning usability sail through this update, actually increasing their traffic through Panda.
Many folks don't want to read lot's of content and sometimes you don't need it for ranking. Often it could be a negative signal.
