For the past two days, only applications from Max Levchin's Slide have appeared in MySpace's featured application page. Smaller developers asked why, the Social Times reports, and found out it's because Slide pays. On the order of around $50,000 to $100,000 per week, these developers say. Facebook does not charge application makers to feature them, ranking apps instead on user activity and feedback. The Social Times notes that MySpace's Sponsored App program could keep small developers from gaining popularity on MySpace. Whatever it takes to keep Vampires and Zombies at bay, we say.

Makers of Facebook applications have seized control over the social network's latest redesign. So who are these mighty developers capable of bending the stubborn Mark Zuckerberg to their will? Among others, the makers of "You're a Hottie," which tops the "Recently Popular" list in Facebook's "Just For Fun" application category — the most popular on the site, according to this handy reminder from FlowingData.

Updated mockups reveal that Facebook has added a new tab to its soon-to-be-released user profiles. It's a small but telling detail that illustrates how the obsessively controlling Mark Zuckerberg has ceded power to independent Facebook-app developers. In his original plans for Facebook's redesign, Zuckerberg planned to integrate the Wall — the place where public messages from other users are displayed on user profiles — with Facebook's News Feed, which is where Facebook serves ads between "stories" about other users' activities. This integration was a way for Facebook to finally serve ads in the Wall, a placewhere users spend a great deal of their time on the site.
