Not really anything to do with AdSense actually. However, the ideal opportunity to refer you to this review I've written about them! Well, you did ask! You can use TLA alongside AdSense no problem.
Thanks syed - I tried to give a balanced opinion of them so you'll find the negatives (acceptance criteria) as well as the positives (good payout by PayPal). Speaking from a personal point of view it's quite a nice little earner each month. The key thing is that it's perfectly okay with AdSense.
