Finding your people can be difficult. What used to be confined to physical locations is now categorized and searchable in your social network of choice. I don’t believe online communities can replace the need for in-person interactions, and people’s interests cannot be confined to a group of categories.
As a developer it’s easy to think your community is a language, framework, or API. While those can help introduce you to other people it’s important to remember we are not our tools.
Community can be much deeper than shared interests. Be your authentic self and let your people find you. Make sure you relate to the human side of community.
