Now, the disadvtages go this way. They accept sites that have pretty huge amounts of traffic and not the beginners. This reduces the morale of the blossoming bloggers. Secondly, they do not support other multiple advertisment agencies. For example, if you are publisher and you serve ads for LinkWorth and you want to do the same with TextLinkAds, it is not possible. Thirdly, the commision they take is quite high(50%) when compared to LinkWorth(only 30%). Overall, it is a good site to try out to add a litle more penny to your PayPal accounts (Conditons Apply: Your blog should posses a pretty decent traffic :) ).
