What the hell is your problem?
I said I didn't even want it to make money, I DON'T CARE, it's a personal project.
Well, one would assume if you have your own server and are paying for rack space/maintenance then you'd prefer an idea that brings in a bit of revenue to cover the costs. We don't know your interests, what kind of knowledge you possess, what the name of your domain is, etc... How are we supposed to suggest something without any information, and if we did have a great idea, even if it didn't make money, than Ginger is right, why would we tell you?
I guess you could go on some freelance sites to get some ideas.
