For you guys who live under a rock (aka don't go on youtube), this "revolution" was started by UberHaxorNova. He does Minecraft and more specifically he does adventure/puzzle maps. Doing enough of them, he got pissed at how the ladders worked, when you would jump towards them, you would just faceplant on them and fall to your doom. You would have to do the so call "twisty jump" to get on them. That's really the whole deal. He says it in basically every puzzle map that includes ladders, in some regard telling Notch (or now Jeb) to fix the ladders.
Take this video for example, it features the meme that Nova has created (pay attention to what he names his map)
