Their platform is ok. It jittered a lot, and I'm really not a big fan of the social graph, but some stuff is good, some stuff is bad, it's on the balance ok.

The problem is that they're selling advertising access to their people. That's all they're selling, via direct ads or graph access and 'sharing'. Impressions. Period. So there's a very natural friction between people who are investing a bunch of dev time and expecting their impressions for free and facebook, who doesn't want you to piss off their users with a bunch of spammy ads without at least paying them for it. So facebook is locking it down, little by little, and all the devs who were used to getting something for nothing are seeing their marketing vector dwindle little by little (unless you pay).

The whole 'review process' I found extra annoying, though. I will tolerate that shit from Apple, but not from facebook.
