What do you think Barack Obama's joining Pinterest will do for the site's popularity, acceptance and legitimacy?

I joined Pinterest a few months ago. Since that time I have really become inspired by the various photos and ideas I’ve seen on it. I have also seen, on other internet sites, posts about Pinterest’s possible legal issues that may arise from people “pinning” and copying photos from other sites, which is how Pinterest works.

I saw on the news today that Barack Obama joined and has done some pinning.

What do you think the President’s joining of Pinterest will do to its popularity and acceptance?
