How many celebrities or high profile individuals do you know of that owns and support Bitcoin? I think if we can get some high profile users, we might get some good exposure going forward.
Personally, I don't think attaching faces of celebrities/personalities to bitcoin will give it a boost. It's good the way it is already that no particular person controls it. This was a reason I so hated what John McAfee was doing with his pump and dump group because of his status a lot of people trusted his judgement and followed him sheepishly. Attaching a known face to bitcoin will make investing in it a personality controlled investment and that's not going to be good.
