The Envato Marketplace is in need of a new pricing redesign.
There are 2 problems with their pricing model.
It devalues the work of web designers and developers. When The Client can get his hands on a Drupal theme for $15, he or she will believe that theming Drupal is easy and that a custom theme can't possibly cost 2K and up.
Unless your sales are over $11,800 annually (or is it monthly), Envato will keep 55-60% of your earnings. And you have to sell your items exclusively on Envato to make that 40 percent. 40 percent times $15 = $6.

The Tuts+ Network is great. I am paying to be a plus member.
But that network is paying for itself quite well: fairly-priced advertisement, premium subscriptions, gullibility of contributors (who get paid little), and storage (and hosting?) on Amazon.
There are a few people getting rich and richer at the expense of many people's hard work and careers.
