What were the issues you encountered? I know a few people who developed side projects by reading through oDesk and elance jobs. I read them time to time to stimulate brain to come up some relevant features to my own projects.
Definitely you will need to have patience to find ones that catch your fancy. Also no one job going to give you idea, but when you read a lot of them, you start to see patterns and might develop linkage that will make interest project for you.
It was over 5 years ago. There really weren't any issues. I just didn't see any common threads that were interesting. Could very well be the type of projects I looked at.
