💡 I have this idea of gathering third-party projects related to Kotlin and crucial for the community which struggle with their development and maintenance (like ktlint and many others), and encouraging people to either contribute by their work or donation. I can imagine it being somehow supported by JetBrains as well, e.g. in a form of a section on kotlinlang.org. The non-trivial part would be to determine which project is crucial for the Kotlin ecosystem (like ktlint, extremely popular) and really struggles to go forward. It could be organised in a form of community voting/survey. What do you think about this general idea?

I'm doing a small casual livestream right now at https://www.twitch.tv/sebi_io – answering Kotlin questions and getting into any kind of discussions you might have. I'm also going to be tinkering with building an emulator for Uxn (https://100r.co/site/uxn.html), a little personal computing stack – and probably the only assembly language I know that has hand gestures defined for each operation 😄
