What is the community’s stance on cross-posting from other sites? Either via direct link or screenshot/recording?

For example, it might be bad taste to create posts which are just links to Reddit threads. At the same time, discouraging posts which are just links to YouTube videos seems a little silly. Of course, you can come up with many grey-areas between these two examples.

Personally, I don’t want to follow links to Reddit because that place is a disaster. That being said, funny things are posted to that site and I don’t see any reason why I shouldn’t laugh at a screenshot of such a thing posted here.
