He actually has a facebook and it's really him!

I doubt that is really him. I don't think he has an authentic Myspace page or an authentic Twitter page either. I highly doubt it. He does not strike me as the type of person who would have a Facebook page, regardless of whether or not he wants to continue acting. He left Home Improvement to attend Harvard, then left Harvard to pursue acting again. Maybe at that time, he was unsure of what he really wanted to do. I think that since he is older now and hasn't been in anything for a little while, he may not want to pursue acting anymore.
