I think it makes a difference whether you're looking for ideas that will do well, vs just having an idea that you would go for as a pet project. I have one of those "just a pet project" ideas which I have been developing for no reason other than my own benefit, and let me tell you, I love finding competition. It's like Christmas every time I find out there's a service that incorporates some of the concepts, and I keep a big document of inspiration that draws between all of them. If your idea isn't unique, you can still succeed, but you have to out-do the competition on something other than uniqueness.
