Serious question, I don't mean to offend (at least not yet ;) ) - do you only ever play DnD? Because this community is called RPGmemes and I rarely (if ever) see anything but DnD.
RPGMemes
Humor, jokes, memes about TTRPGs
Personally, I also like genericizing D&D.
It's a shorthand for folks outside or new to the hobby, it skips a hurdle to talk to people about other RPGs with those people, and it weakens the brand identity. Considering how much D&D has coasted on brand identity as the game suffered, I'm all for that.
I'm less likely to do it places like here, because it causes more confusion, but still. It's fun to say, "Pathfinder is a great way to play D&D." :P
I prefer TTRPG because it doesn't give free advertising to Hasbro. Even if most people know what you mean, someone googling D&D ends up at Hasbro's product.
I use RPG. CRPGs can have a more-than-four-letter-acronym.
Mostly play PF2e nowadays, but I'm open to other systems. I get the feeling that some people use DnD as a shorthand for all TTRPGs tho
What is stopping you from posting non-D&D TTRPG content?

Never played DnD but the US community is 90% DnD so...
I play Shadowrun and Blades in Dark for now.
Yesterday, one of my players just plain forgot that we scheduled a game.
Luckily, the party was split up doing downtime activities anyway, so we decided that they simply could not locate that character quickly (time was somewhat of the essence). Near the end of the session, the party realized that they need that particular character's alchemical expertise, giving them a great reason to actually go look for him.
For DnD, I normally aim for six players, and I run if there's at least four present.
Knowing that the game will go on anyway without you is really good motivation to not flake out (I speak as someone who flakes out a bunch.) - and DnD is a very easy game to just have someone be not present for a week.
