Maybe not your generic "discussions", but at c/askscience we can discuss interesting (and more or less absurd) scientific questions and hypotheticals, if you're into that kind of thing ;)
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !askscience@lemmy.world
This is more of a support question, related to using Lemmy. Please see the sidebar for a list of communities that offer support. Removing under rule #3.
Is asking what everyone's favorite communities are a 'support' question as well?..
Kinda defeats the point of an 'ask lemmy' community when the questions are ovepoliced like this. Not a very welcoming environment for asking genuine questions.
