MMM = surefire traffic.
I added Maverick Money Makers to my IM review site (basically saying it's pure MLM scam and to stay away). I've been getting 3X my normal daily traffic since I did the post - from those searching for info about MMM.
I'm sure that if anyone did a blog post they'd see a similar traffic spike. Can't speak to the quality of the traffic, though.
I'm sure I'd see some real gems if I had commenting turned on.
