Those domains have been around since forever (also https://orionfeedback.org). I guess it was easier to just set up a new platform instead of integrating it, or building something from scratch.

I haven't checked in a while, but I'm sure there's been conversations about this on discord as well (https://help.kagi.com/kagi/support-and-community/discord-ser...). I'm too busy to read up on every little thing, so I'm glad this happens elsewhere, off-site, and I just get the big changes through my RSS feed.
