I've talked to a select few of you re: this, but I want to throw open the barn doors.
There's a newish website called
momentile. The premise is this: every day, you upload a photograph. At most one photo per day, and once it's uploaded you can't change it. Other users can caption it, but only get one shot at doing so.
It could devolve into a shitty pictures-of-my-kids-dog-and-drunk-friends kind of thing. Or it could be a cool collaborative art project driven by time pressure, spontaneity, and transience.
Still in the α phase right now, so if you want to participate let me know your email address (comments screened) and I'll send you an invite. Even if you're not interested, the link above will let you see the most recent momentiles.
