In buttons titles in the post menu, majority like deleting, editing bookmarking, etc are in lowercase, while the Like button’s title text is uppercase. This may be nitpicking, really, but I first came across it when looking at the locale affecting the text saying ‘this post arrived via email’.
For example, some locales here are uppercase while the others are lowercase. Buttons elsewhere in the interface are mostly uppercase. Was there a reason why these were left lowercase?
