I don’t use it often, but when I do it saves me hours.

For example, I used it recently in a large project that had no CI. The build failed, and I could find the first commit it failed on using bisect in a couple of minutes.

Well, there’s this place:

• link for kbinauts: New Communities
• link for lemmings: New Communities

My new community got quite a few subscribers from there. Just make sure to post relative links using both the Lemmy and kbin routes (/c/ and /m/).

EDIT: oh, I almost forgot, there actually is a site for community discovery: Lemmy Browser. I don’t think it currently lists kbin communities but we could ask them to (or if it’s open source, someone could implement it).
