Following my long experience with where I was the only admin and the only one allowed to add images to the group, I'll run a similar group dedicated to street photography.
Do we need yet another street photography group? Maybe, maybe not. Time will tell.
What a I can tell is that if you watch or join the group, you will see at most a handful of images per week (beyond the initial influx of oustanding street images from my years here on dA), and that these few images will have been carefully selected.
I'll focus on modern street images, without excluding more classical ones. As a consequence, you will find much more color photos than in other street groups.
Please feel free to join!
