Yet another ad bar that pays you to surf the Web. Has some advantages, but my least favorite of all the bars. You can earn points in other ways, such as playing games and signing up for programs. However, the Spedia bar is a lot more finicky about awarding ad points than the other programs. It seems like they built so much fraud-detection into the bar that it isn't fair to the honest customers.
Referrals are one level deep.
Pay rate varies according to ad revenue, but has been running about 48 cents per hour recently. There is no limit on the number of hours you can surf. Barely recommended, because of the unlimited hours and the games. Some of the others may be good, but at the current time they haven't released their ad bar to the general public, or they have reputations for poor customer service. The programs listed above are the only ones I use and recommend.
