The Fb Profile Picture!

Mine was taken at my son's last birthday party. It was complementary (of course.) You never see anyone offering the worst picture of themselves; or do you? My favorites are the people who have no image at all. What's going on there? How bad could it be or did they just join Fb to check out others without exposing themselves? If that is the case, then I cry FOUL!
The other profile pictures I enjoy are the "odd" ones. Like my former love interest's picture... it was a little creepy, but then again, so was he. I have a dear friend who rotates all sorts of photos as his profile picture, which actually keeps things quite interesting, and I look forward to the next one.
So, I guess no matter what you have up for the profile picture, it does really speak louder then just about anything eles you have on your profile. What do you think?
