I have the opposite problem. Too many ideas. And mostly they are non-commercial "open source" kind of ideas. So hard to justify working on with work/family commitments. But these ideas have come as a result of doing side projects. This is my main pet idea, feel free to do it: I am very interested in the idea of sites that provide cloud functionality (e.g. a budget app, a todo list, a calendar, a document editor etc.) but the user controls where and how the data is stored. I was thinking of making an app that does a lot of those things (budget todo etc.), and you log in via Dropbox - USING THE CLIENT SIDE API. So there is no middleware server, just a static site and then Dropbox API connected via XHR requests. The next step is to integrate 10 other Dropbox-like services, and eventually open it up to be extendable so anyone can bring their own service if they want full control over where there data is stored. Then other people can write more apps for the eco system. Eventually you will be able to say "I want this mail client, and I want to store my data in Azure", or "I want this todo list, with my data stored on my server" and it will be super easy to do. And by easy I mean the app developers don't think about storage other than a call to .store(json), and the user doesn't need any technical knowledge to make their choices. This is to bring the spirit of desktop apps to the web. Just because we use the web for convenience it doesn't mean we need to be tracked and have it in a nice schema with other people's data for spying on. The gold plating is to integrate with some work that has been done recently on a document format for collaborative editing of documents. It was posted on HN a few weeks ago but I don't have the link to hand.
