Hi. I had never heard of swagbucks, but I did check it out, including this in-depth discussion of it:
How to Win Swag Bucks
You really have to be careful with these things. Any site that wants you to install a toolbar is iffy -- toolbars can be very invasive bits of software, I've even seen toolbars flagged as viruses (most recently from some coupon site my wife thought was cool). Sites heavy in advertising and third-party connections and referral pyramids are also typically very invasive, using tracking cookies, selling your personal info -- anything they can do to make a buck for themselves. And most people do NOT make more than $1 an hour on any such site, unless they pester their friends and get them all entangled in the same mess.
The trouble with shopping reward sites (ebates, etc) is that you have to spend a lot of money to get a little bit back.
It will be good to see other people's stories about various sites. I always strongly caution people away from online "make money doing nothing" sites. I have programmed a few search/toolbar/referral sites personally, and will never do so again, for ethical reasons.
I realize it's theoretically possible to make a few $ on gimmicky websites ... maybe save $10 on Christmas gifts ... but I guarantee that the same time could be put to better use almost anywhere else, with less risk to your privacy or sanity.
