No, its not worth it. It was a lame idea in concept and its already being exploited. The bots that Vyl is talking about constantly scan the RMAH for items posted by mistale for .01 rather than 1.00 They nab it up before the mistake is even realized and repost the item.
Anything concerning gaming and real money is and will be exploited. These bots drive down the cost of the items, and frankly, I can grind hell mode a little longer if I need just one more piece for inferno. I can farm pages and books for blacksmithing and jewelcrafting a little longer rather than the immediate gratification of having the skillup NOW.
I guess for the truly impatient it might make a buck or two. But I just dont see the benefit and it will probably fizzle out to items only being worth a minimum amount because of the botting and because of people actually wanting to be patient.
