Phantom thief & vigilante social talents

[Wyrmfoe]

Is there a limit to how many times a Phantom Thief can take a vigilante social talent in lieu of a rogue talent?

The wording from Phantom Thief is as follows:

"Finally, she can select a vigilante social talent instead of a rogue talent, except for social grace and vigilante social talents that would require her to be a craftsman or professional."

Is the above meant conversationally, in that whenever I might take "a rogue talent," I may take social talents, or is that meant to limit the option to "a" single rogue talent?

No limit. You can take as many social talents as you like. Although between major magic and combat trick, there is a lot of competition on phantom theif talents.
