"The proceeds will be donated to Child's Play," Valve UI designer Alden Kroll notes in the announcement. "We have no interest in making money from this, but we do need to cut down the noise in the system."
Additionally, the browsing experience has been altered. "The next time you visit Steam Greenlight you'll be shown a smaller, manageable list of games that you haven't rated," Kroll said. "This view is a mix of popular games and new games to Greenlight." Both of these initiatives are an effort to manage the exploding population of games on the service, from different angles. Greenlight has received over 700 submissions since its launch on August 30.
