I play around a lot with photography and like to think I'm good at it (though really I just don't have the patience or energy to be that good at it), so I joined a website called Redbubble.com where I can display and/or sell my photos. Really, this is just for fun and very unlikely to produce any profit, whatsoever. But still... nice to think about some of these images on the face of a card or mounted in someone's hallway - even if it's just my mom's. :)
Also, I know a lot of you have taken some amazing photographs, so perhaps you should think about joining as well. Did I mention it's free?
