every photo on Facebook is user generated. an overwhelming majority of them are bad photos. Facebook is completely aware of this.
as such, it would be an irresponsible design choice for Facebook to create such a huge presence for those photos, like the design proposal does. likewise, it is irresponsible of the proposal author to only use high resolution stock photos of decent looking people for their design.
perhaps my original post was not crystal clear. in retrospect i maintain that it was a fine explanation, albeit terse- and out of context given my misinterpretation. regardless of my post's clarity, your response makes you sound like a dick.
I respectfully submit that had what you meant to say been so clear, or had you followed your own advice to "read both posts carefully", perhaps you wouldn't have made the mistake twice.
