I don't know if it's just me, but the sharing panel in the rant detail view makes me cringe. Not a designer but I've been told that elements are not meant to be displayed in such a way (e.g obscuring other view elements like text). I don't think it looks ugly, it just sends a tingle down my spine. To me it seems like an "in your face" approach to encourage users to share. I hope this is understood as constructive criticism.

Possible solution: show the exact panel that is in use right now but with a background and only if users scroll upwards(!).

Had to get this off my chest. Have a nice day folks.
