Not surprised if the memes played a role in keeping meme-meisters away from 4e, though it should be mentioned that those memes were almost always invariably followed by someone posting a meme of "Batman is EVERY Alignment."
And those people were wrong, because Batman was never, ever, Lawful Good.*
Not even campy, Adam West Batman.
*As a fictional character who has existed for almost a century at this point, and has innumerable authors in multiple media, sure, somewhere there might exist a LG Batman; but in all the many incarnations, he has been at best a NG.
PS- No, I am not posting this just to stir up an argument about the best superhero ever.
