Honestly, I'm not a very photo oriented person, and I despise having my picture taken (I'm always blinking, or have one eye half open or am making a stupid face, or something right when the shutter clicks)... so it's not something that I personally would get much out of.

That said, I think you're right... for some people it does have value. Whether or not it has enough value, and an accompanying business model, to build a successful business, is TBD.
