Contribute regularly to an online community

When I first got the internet I joined a number of online forums to learn about all kinds of different topics. As I’ve gotten older, all of those original communities have disbanded and moved on. I miss learning about new things and sharing knowledge with others, and my online interactions these days are nearly always confined to work topics.

For 2020 I’d like to start contributing to one or more communities. I don’t expect to be as profilic as I was when I had more free time, but want to make an effort to help more people.

I don’t really have any measurable targets for this goal, as it feels a bit odd to award myself for interactions with other people.
