IMO, this experiment would have worked on LinkedIn. The targeted ads I see when I'm in there are way applicable to the "professional me" than FB or Google ads.

LinkedIn just makes more sense for a B2B marketing campaign. I'm sure the numbers (of users) are all smaller, but the user characteristics that lead to getting shown an ad are better discriminators in the B2B case.
