Warren thinks it's pointless to photolog your life if there is no accompanying information.
But my personal experiment in photologging/lifestreaming (I take a photo with my cell phone every hour on the hour, at whatever I'm looking at at that moment, and post it on Facebook) has no caption (other than tagging people in the photo) and has seen some success as an art project. People like it as something mysterious. I've even gotten an offer to put it in a gallery.
What makes it art, I guess, is that people are challenged to construct their own story from the images, with no other information provided.
So, that's the comment I would have left on that post if comments were enabled (and if I didn't keep getting a 403 error whenever I tried to get to warrenellis.com directly rather than through my RSS reader).
I think maybe it's the 'Too Much Info' clause of life. If a person posts pictures of everything everyday, how do you pay tribute to the more important things of that individual? It would be easy to pass up the gems in a stream of images because of a myriad of posts of their meal, their tired friend, that crazy person you always sit next to on the bus, etc.
Pictures and images used to be created with the express purpose of passing on what someone thought to be highly noteworthy., i.e. 'a picture is worth a thousand words.' But what would be the result of giving a thousand monkeys a thousand digital cameras? Warhol? Personally I think Ellis is testing for fanaticism with this thread...
