No, not per se. Jetpack is what is adding the Google+ profile link to the page, which is absolutely fine. It’s just that Twitter Cards Meta’s method of pulling out the post content is stripping out everything *but* the Google+ profile text.
I noticed that the Open Graph plugin I use also uses a routine to pull the post content for the description tag and it returns the post content as well as the “Google+ Kevin Sutherland” text. In most cases, the post content is so long that that part doesn’t actually make it into the Facebook Open Graph Description.
That suggests to me that maybe Jetpack could have a better way of inserting the Google+ profile link so it doesn’t show up along with the rest of the post content when plugins query the database.
