I agree about the thumb covering the content, but in the short period of time I've spent with the app, I've found myself swiping from the middle - mostly along the bottom-edge of the screen. And I guess the physics-driven carousel hasn't been a huge problem yet since I've mostly been swiping to pan through the content for skimming. Guess that's the challenge of any interface - that different users may approach it in entirely different ways.
Anyway, nice study on the interaction, and thanks for your reply.
