It's a place to share photos of what you have cooked. I enjoy food photography, and I wanted a place like this to share my photos. It's not about recipes, there are plenty of sites for that.
Seems like it is just not for you, too bad. Your comment would be more useful if you could elaborate on what it is that you find useful, though.
If I had to guess, it looks like it's a competition for dish presentation? So, it'd get its energy from the ego and competitiveness of the people who participate. No idea what they're looking for for a revenue model, unless they're trying to serve as a cooks' competitive photo-portfolio.
I couldn't agree more. Pictures of food are really not very useful. If the pages contained actual information, maybe the recipe (some pages do) then this might be useful. Also, I think some type of search is absolutely necessary.
