I've had more than 6 million Youtube views plus around 60,000 subscribers/fans/followers (Youtube, Aweber, Facebook, Twitter combined) and I earn money using the freemium model (free Youtube videos, free eBook; premium videos and premium ebook for sale on my site).
I've long been offering up the monthly membership at $97/month but got interested when Russel Branson's book said that his $47 membership had 4x as many conversions as his $97; so I gave it a go. My results are, out of 1,000 exposures to my sales page in 3 variations only concerning the price: 97 at 2.54%, 67 at 1.61%, and 47 at 1.4% so we can say that it's linear but inverse and contrary to the classical supply and demand model. Wow. So now I regret that I wasn't able to find a better price to increase conversions and that in a way, I wasted the extra money on the table during the test; but I'm also happy to know that my higher price point makes the most. What should I test next?
