I think this is a great idea Paul, it's not a problem for me as I have had a creativity block for what seems a lifetime now lol and if anything I feel I comment too much without displaying much of my own stuff.
The only problem I see is where there is not much to say about a photo, there is one that Tedz seems to think should have had some comments, personally I can't find anything constructive to say about it - it's a good picture, end of.
Overall tho, great idea, I think you should implicate it asap
