I have a hunch, and a hypothesis, that I'd like to test with this audience.
The hunch is this: we're all here because we aspire to become better photographers, and we want critique and helpful commentary, but with close to 25,000 members, posting a photo up for C&C in Light Box is quite a bold step, and at least I don't feel quite "ready". The internet can be a brutal place, after all, and we don't all have thick skins.
So the hypothesis is this: if there was a way for you to be teamed up with a small set of photographers whose opinion you respected (but who weren't intimidating pros), would you be more willing to share your photos? In particular, I wonder if being in a smaller group which stayed together for a few photos would not lead people to critique more, and be more willing to be critiqued (because the space would feel smaller, safer).
Feel free to comment, or even just +1 to in case you think I'm roughly right.
(I'm toying with the idea of building a web app to explore this concept)
