Hey IH! For the past 6 months I've been curating The Hive Index: a directory of online communities.
I got really inspired by the Indie Hackers community when I started my bootstrapping journey, and wanted to make sure that online communities are accessible to anyone who wants to find them. So I started keeping an organized list.
By now I've expanded it to include almost 500 communities across 70 topics. For each community, I tag it with platform + features (like forum, chat, newsletter, perks, job board, etc) so that folks looking for communities can find one that fits their needs.
It's been a fun little project to work on, and I've been enjoying growing it over time. I've definitely met some very cool people in the process, and it's inspired other projects for me to work on.
If you're running an online community, I'd love to list it! Also, if you know any good ones that I should add, or would like to request a new topic to curate, please let me know!
