The problem is that even the funniest, best made and most entertaining ad ceases to be anything but an annoyance when you see it for the 30th time in an hour.
TBH, this initiative scares me a little as I suspect one of the design bullets will be to make the "LEAN" ads more difficult to block by making them less distinguishable from the main data stream.
