Concept: a mobile app where you input ideas you have with the following 3 pieces of information:
The app would function like a cross being Twitter’s stream and Instagram’s social features (e.g., number of likes, following people) where people can “like” your ideas so you don’t waste time building something nobody wants. The app would automatically sort your ideas by popularity. And maybe there’s a “popular” feature like Instagram where you can see what the most popular ideas are.
Easy peasy, lemon squeezy.
The target market would be anyone looking to start a business or just spend time on something they want to spend time on.
If you don’t get any likes on your idea, your idea is either really dopey, or you don’t have enough friends (just kidding. I like you.)
