There is just one problem, Jetpack screws up your Open Graph data. Thats what I recently noticed.
Even though they tried to fix this in v2.0.3, this problem still exists.
Example: OpenGraph Tags in header:
How to disable Jetpack open graph tags
// remove jetpack open graph tags add_filter( 'jetpack_enable_open_graph', '__return_false' );
Force enable OpenGraph Tags from Jetpack wordPress plugin:
add_filter( 'jetpack_enable_open_graph', '__return_true' );
That’s all.. And you should be all set.
