Not sure if this has been addressed or not. However, I like the comment request system. Giving and recieving is always nice but how about the ability to narrow the pictures you get requests on to a certain category.

I, for example, am into CGI so I like to comment on fractals, abstract, computer gen, etc etc and maybe I dont really like pictures of cars to much. I will comment on a pic of a car if it askes me, yes but lets be honest here. Is it going to be a real, sincere, and useful comment? Or an "oh thats nice, lets find something I really enjoy," comment?

Maybe I like to see and comment on all pictures and I can select all categories.

This just comes to mind because I get comment requests for a lot of different types of images. maybe i know nothing about photographing birds or you know nothing about CGI so we both loose besides the fact of that is a nice pic I will say so or eww thats ugly I will just not say anything.

Not a bad idea.

If you don't feel qualified to comment on an image (or just have nothing to say), just remove the request and it will go to someone else. I think that if you do this the system will realise you now have no comment requests and generate a new one for you, so if you just keep removing the requests you should get one you want to comment on sooner or later.

The problem I see with your suggestion is that the idea is to get more requests on image that aren't receiving any comments, so there may not be enough of a particular type to go around; on the other hand I guess there is no point sending people requests if they aren't going to comment... I guess it just depends on how easy your suggestion can be implemented.

Yes, it does carry those flaws. I did not know that if you canceled it, that it went to someone else.

It may not work exactly like that. But unless someone comments on the image, it still has the same low number of comments so the system logically would generate another request.
