The concept behind the freshly launched Everyday app is extremely simple - take a picture of yourself every day. The introductory video is pretty amusing and just a little bit bizarre; well worth a watch even if you've no interest in the app. While I've no personal interest in creating a repository of images of myself (i've done it before) I think the app appeals to peoples most narcissistic sensibilities.. which means the likelihood of it being a popular app is incredibly high.
