Generally, these offers *do* work, but:
- You have to put in your email before you even find out the details, and they spam you into the stoneage
- You have to put in five friends to invite, which they also spam into the stoneage
- You have to do some "offer" like getting a trial of a magazine or something
- Five friends have to do "offers" as well and go through the same process.
So the end result is that it's too much work to jump through all the hoops to actually get it, and so 99% of the people who sign up end up not doing all of it to get the iPod. If a choice between working and doing all the crap to get the iPod, working is a better deal.
I have a friend who's gotten tons of monitors, ipods, etc from these offers, but he's also very careful, and he actually started running one of those services himself, and he's selling the software he wrote to run such sites.
