It feels good to contribute back to the community. I've gained an incredible amount from the open source community over the years, so I'm doing my bit and contributing back. I have no intention of making money from this service, I have bigger fish to fry! Until this service starts costing me a significant amount of money, I'm happy to keep it running. However, because it's an incredibly lightweight app, it should scale to handle incredibly high loads of traffic cost effectively.
