If I were an indie app dev building a similar product, then in addition to all the questions of business strategy I would try to bake in graceful abandonment from the start. That is: make it a paid sync service (as Gruber would've in hindsight) but build the client such that the sync service could be easily overridden, and pointed at anything that would support a particular API. Then if I have to stop supporting the app, but I have users I still care about, I can just unlock the sync service override, publish the API spec, and give people some time to come up with alternatives. Though I guess that doesn't solve the problem of fixing bugs in the app itself. Especially if I might not have time to babysit an open-source app. Are there any examples, in iOS, of apps that were open-sourced and are controlled by some kind of committee or foundation and still kept up-to-date in the app store? What's the lightest-weight version of that that still keeps it totally free? (I bought Vesper over a year ago and thought it was nice but it didn't become one of my regular-use apps. No biggie: I've long been a DaringFireball reader and I'm happy to throw a few bucks Gruber's way. Plus, I was really hoping the "quality paid apps" model would work, sigh.)
