I can appreciate the problems of both GIVING and TAKING comments. I'd prefer everyone participate, but that's not realistic. With too few hours in the day, you have to draw the line somewhere.

Even if I cannot  comment on each submission. If I see something (good or ill) that needs commenting, I try for something to say. Not everyone has as much time to commit to this endeavor as me, or others. 

So if one wants to stay, they're welcome to!  More the merrier!

I cannot save the world. Only my little piece of it. If we all act together, we can save the world.--Nelson Mandela
