I have complained about the instagram logo for years, but now I'm eating that. This icon is meaningless and will stick out like even more of a sore thumb.
1. I never liked skeuomorphic icons, so I'm biased. I'm not a flat fanatic, but it definitely goes way past the sensible middle ground for me.
2. It's just so out of place with everything else on my phone (android). It gets my attention every time I open the app drawer, and I mean that in a bad way.
