Just want to take the communal temperature on this one -- personally, I get a painful little tug in my soul when I see the same memes I just saw on FB getting posted here. Esp. when they're the entire content of the post.
Memes are life itself, don't get me wrong. RI is a discussion forum for text-based conversations between carbon-based lifeforms, though.
I don't want to publicly shame people. If only for the sake of avoiding the irony of interrupting the conversation with a low-information post to complain about low-information posts interrupting the conversation. Moderation will always involve recursion, but too much is too much.
But, how little is too little? To you. What's the minimum contribution?
