I think you've done this backwards... problems that need solving tend to come with their own niche - the people who want the solution. I actually intentionally worded it backwards from the usual as a minor form of headline bait, which failed. The app really should have broad appeal among people who frequent the web in general. That group of people is just too varied and spread out to help each other find links through Jellly. Hence the need to focus on a smaller, more closely knit group. Not all apps fit the "solve a pain point" model that paid web applications go through. While pain killers are great money makers for sure, sometimes you don't know you'd want to use an app till you've tried it and see why it would be useful. These apps have a lower chance to succeed I guess, but they can be great when they do. I know there's nobody dying to have this service. But Twitter comes to mind as another application that people thought was mostly useless. That is, until some of them used it (I know most people still think it's useless, but many obviously don't). Advertising fits perfectly here, since the service is there for relevant links. The advertising would consist of relevant text links, similar to search ads. Mass adoption would be necessary for large profits, but I believe it's possible to break even much earlier, using advertising networks to start advertising early on.
