Everything on Squidig is submitted by Squidig users, and after they submit a Lens, other people will read it and give it a thumb up or down. If that Lens receives enough positive votes, it is promoted to the Featured page.
Squidig also offers each user their own "Featured" page, and the Lenses promoted to their own "Featured" page page are determined only by the votes of the people this user has previously selected - these are what we call, the user's Lensfans.
