Okay, I went to the imtiny.com and this thing is nonsense. It's essentially a pyramid scheme. You're promised huge traffic when you get to the seventh position. The only problem is that there is no basis in fact for this. Just like in a real pyramid scheme, you have people drop out, modify the list to include just their own sites, screw up the instructions, or just can't get enough people to join (especially since most people don't have any real traffic anyway - so who is going to copy your list?). Just like in a real pyramid scheme, you end up having to sign up half the world's population to get any money.
And if you check out WHOIS on the domains on his list, guess who most of the sites belong to? So by copying the list you're just running a free ad for his sites!
So if you think this guy is really on to something, how come his own site is ranked
#13,909,083 by Alexa? That means he gets about 20 hits a day. It's a total waste of time.
