Okay. The "Yo dawg" meme comes from Xzibit(I can't spell the goddam name) who featured on the show "Pimp my ride". When he had pimped the car he usually added something that inyerested the car's owner, for example a video game. And he would always say something along the lines of: "Yo dawg, we herd you like X, so we put an X in you car so you can X while you drive."
This later became a meme focusing of things that were in other things. Like, if there was a bike standing on top of another bike the "Yo dawg" meme would be used with the text: "Yo dawg, we herd you like bikes, so we put a bike on your bike so you can bike while you bike."
This brings me to your comment about the post you posted has been posted in which a "Yo dawg, we herd you like posts, so we posted a post that you posted so that you can comment while you comment." or something like that.
