I don't take pictures, post or submit them, for the purpose of getting attention, but for this group in particular, I like to participate in the spirit of sharing images that catch our eye, and have personal meaning for us. I love looking at the pool and seeing what other people see. It's fascinating and inspiring.
Getting picked is just gravy - good, drippy, beefy gravy, to be sure (probably on top of home-cut fries) - but the process of seeing, creating and contributing is really the main purpose: the joy of sharing our individual and collective visions of the world around us.
(Although, I admit I keep going back and looking at the group page to make sure I didn't just dream it)
