Get more open source developers for Aragon

I came across this project https://human-connection.org/ which is a a community organisation (gGmbH) and they are dependent on donations and free developers. So they came up with some ideas.
For example they are working with Universities because some of those universities the students have to work on an open source project for a semester or so to get credits. Also they are creating youtube tutorials for developers where they show how to start helping out in github. also in github they mark simple task so people know which are easy for beginners and which are hard.
They say lots of developer like open source projects because they can learn a lot and they can build up reputation. I think those ideas could help aragon and any other open source projects as well.
