On Flickr, there is a great tag to watch called whatsinmybag where people with purses dump them out, snap a photo, and use notes to describe what's everything is.
I would love to participate, but I don't carry a bag or purse. I do have a set of things I would call my 'Every day carry' items.
So I propose a new flickr tag called everydaycarry where those without bags or purses can post and describe what they wear or keep in their pockets during the day.
