Mark Zuckerberg and Facebook platform czar Adam D'Angelo announced new limits on developer spam last night. Facebook used to allow app makers to send 20 friends application invites a day. Developers are now seeing limits of around 8 to 12 per day. Facebook's platform minders also changed the format of invites, moving an unsubscribe link up. "Top developers" hate the news, according to Inside Facebook.

"While this change definitely curtails the ability of low quality apps to spread, it doesn't allow high quality apps enough channel access to thrive," Inside Facebook's Justin Smith writes. High quality? Why doesn't Zuckerberg just get rid of every app besides Scrabulous? That seems easier.
