Poltifake.org was a satellite website of the now defunct meme Motinet network, with a bent toward comedy and satire and no-holds barred debate. (So I am told, though I was never a part of it myself. But it appears it has fallen to me to carry the torch. I now use this stream as a hub for a curated selection of both serious and satirical political memes. -better_call_sloth-)
