Facebook is rapidly getting jacked up. It's not one thing, it's everything. A melange of distraction and aggravation (and privacy issues) that's making me lose faith in giant social network applications. Facebook was the clean, goodly cousin to the debauched circus freak that's MySpace... but now it's getting more difficult to tell them apart. I'm not talking about design or interface, I'm talking about overall noise and attention.
Without getting into the details, Facebook needs to be careful about the quality and variety of applications. There are nearly 30 Flickr applications for instance. All of them suck. People want the functionality that F8 provides, but there's only so much that one can absorb.
