Today I've asked myself: what are the best communication methods/channels required to reach a maximal audience of people in a minimal amount of time?

As I come from a multilingual and multicultural background, I'm trying to research communication methods/channels/tools for bigger groups of people online.

Currently I'm trying HackerNews, Reddit and Instagram.

Planning to connect with github & others. Let me know if you know communities interested or of interest.

Thanks & bestest of bests!
