To me, a great idea is one that is solving a big problem in a large market. But that alone is not enough because if you don't execute it, competitors can come in and perfect your idea to its full potential. This problem usually tends to exist because nobody has solved it yet or has not solved it in a manner that is practical enough for the masses to pick it up. The fact that your ideas are implemented exactly as you thought of them confirms that if the company that is currently doing this becomes successful your ideas are good. If the company doing your idea is being successful it confirms the market exists and I would look for innovative ways to improve on their offering - or execute better than they do. You want a strategic advantage when entering the competition. It would also help knowing what kind of team/resources they have available. So that if you show up and take market share how quickly can they respond?
