I didn't actually think anyone would notice since I wasn't particularly active.

Fwiw I noticed pretty quickly. Pretty sure within a few hours of when you left. I was going to see if anyone knew if you were okay, but I always had the impression you didn't really like me, so it didn't feel like my place to ask. Glad you're doing what you think is best though. I hope you find somewhere with the more diverse set of viewpoints you're after.
