Thank you very much for this post! It helped me a lot. I suggest caution with using browse.feddit.de though. They do not include all instances - like for example my home instance reddthat.com - you might miss a great community because of that.
EDIT: Now reddthat.com is back on the browser again - Instances could get dropped due to long response times or rate-limiting issues, so depending on the time you search you may get different results on the Community Browser.

I just thought the same thing. This cannot be true. I refuse to believe it
