I just had a new thought as to why I'm not really feeling this cover. Although I get the Twitter-theme and the resulting, deliberate semi-amateurishness of the photos, I don't really see how it's specifically a Twitter theme.
I mean, although amateur photography (of oneself) inevitably comes with Twitter, it's not really what it's known for, is it? After all, Twitter is first and foremost a blogging tool, not a platform for photo sharing. If you want to have an amateur photography-theme, fine, but let's just call it that then and not throw in a trend just for the sake of it. Or how about Facebook? Surely FB has more to do with photos than Twitter?
Ah, well.
