Historically, we’ve had some light-heated debate and “play” with “should there only be memes in the meme thread?”.
So let’s talk about it.
I think that the meme thread should be only memes because
it is nice to get a notification about a new meme and to arrive in the thread and find that it is indeed a meme.
It’s nice to have a collection of memes that you can browse through
(Pedantically) The title is “the Meme thread” not “The talk about memes thread”
Historically this is what it has been, and generally attempts to keep it that way have met approval
I feel this counters
" bit of discussion, reactions, and even meandering isn’t going to hurt anyone."
… actually it directly messes it up. It makes it into “no longer a thread with memes in it”.
“Splitting off non-meme discussion into separate topics just clutters up the forum more with extra threads.”
This is the whole point of threads: keeping topics clear and clean. Otherwise why don’t we all just go to chat and talk about whatever we like in-line?
“Who’s to even decide what really counts as a meme?”
It has never mattered. Like many things in life, it’s a grey line, and a lot of tolerance and acceptance applies. It’s the principle that counts: come to the Meme thread to see memes.
(I have not countered “coherence of discussion” because that is a valid reason for keeping discussion in this thread, but I feel it is massively outweighed by the other considerations).
