It would be a "winner" to me, not only because it played a "minor even completely useless" part to your life but because it would be interesting to even a small sliver of people online. Look at the long-tail on a site like this. You could host it easily without major snags for three hundred bucks a month. If you only play a 0.5% margin for 10 years this application could very well pay off. It's niche I understand, it doesn't have the mass appeal of the "major" players right now. But consider the vast amounts of people that are getting online each year. That niche sites user base grows proportionately. And the real kicker is that a niche site has a very narrow set of users. Making them easier to profile and easier to sell adverts too. Think of the deal you could make with TheraFlu or Tamiflu. Thats why its a winner. If everyone waits to make the next big thing then most of us will be waiting the rest of our lives.
