I have recently joint the Streettogs Critique Group on FB.
I am not a fan of FB, but this group works. Mainly because of it's rule: one can only post an image there after giving a meaningful critique on at least three images posted before.
Unfortunately, this is where our beloved DA (and most of other web sites) fail miserably: one rarely can get any meaningful feedback here!
The most one normally gets is absolutely useless "Nice shot!" or "Great catch!" etc. Arguably, those are not just useless, but misleading and harmful. Provided, one's aim is to grow as a photographer.
Not all critique in the group is top quality, naturally - it is a group of aspiring photographers. Very useful, nonetheless.
But, they have once a month a "guest critic", and in October it was Richard Bram from In-Public. That was a blast! And by itself worth the "price of admission"!
I would love to see more of DA street photographers over there!
