Hi, I'm considering how to put together a contribute to open source contest, which will gets listeners of my podcast, but also whoever is interested, to submit to their favorite open source projects as a contributor. Thinking of offering prizes (possible multiple) based on pull requests, bug filing, documentation writing.
Want this to be a fun, and successful, contest over two or three months. I know some Nextcloud employees told me they once tried a contest and felt too many submissions were questionable at best in terms of effort.
Maybe you could narrow the field a bit by identifying projects that need help (have actively expressed desire). That could help avoid the Nextcloud issue you mentioned. Limit the contest to that list of projects.
