I've never understood why people randomly put really big pictures of their faces on things, with no context/tag/info, it's just a face, not even "Hey, this is me" in the sidebar.
I find it boring to see an apple with a writing: "Eat it!". I guess I can figure it out myself what to do with an apple.
I think it's great to know who you are dealing with, I have a picture of me on my business card as well. Maybe you should concider it.
