I imagine that it is a particular crowd that is present on lemmy that holds on to this one, as I have not seen a Loss meme since 2011. Probably older americans working in tech is my best guess; especially those who consumed web comics from back in the day.
In my opinion reddit was bad because of the closing of the source, and centralization and administration by a single corporation interested in profits, which results in the cesspool we know reddit as today. it wasn’t bad because of the format that lemmy replicates as a link aggregator, so I agree with you on this point.
