Another thing I don’t get is people posting questions and then never engaging with the comments. Not answering follow-up questions or up-/downvoting answers.
On Reddit those were often bots attempting to establish an account with fake posts and karma before using it for spam. Not sure about Lemmy.
I’d definitely notice, mine is less than a year old so I still remember thinking about which side I wanted the refrigerator to open towards.
Plus right now it opens facing the rest of the kitchen area/counter and that works for me. If that suddenly got reversed it’d be a noticeable and annoying change.
