Stuart Bramley mentioned on Twitter that IBM i should really have it's own "app store." He may be on to something there. There's oodles of IBM i content on the web, from how-to's to fully functional applications someone has built and shared with the community.
I don't think anyone has tried to consolidate any of these tools into a community repository. If there is one, please let me know. But if one didn't exist, I'd be lying if I said I wasn't interested in helping to facilitate one. If anyone in the IBM i world wants to weigh in with ideas or offer some help, or heck if you have a handy app you'd be willing to share/sell then please let me know.
My first thought...wouldn't it be awesome to browse and pull an app directly onto your IBM i similar to a PTF download in Fix Central? Why, yes. It would be very awesome.
