I used Squidoo for back links not as a revenue source but there are people who has 300 - 400 lenses and used to earn 1000+ usd per month from Squidoo. It used to be one of the easiest if you have a Paypal account which can receive money.
But not anymore. Something has gone wrong. Maybe Squidoo Alexa ranking dropped from 32 to 420+ has to so something. Clearly they traffic dropped and they deleting lenses right and left and more real authors are moving to other alternatives and their own blogs.
Anyone here used to any from Squidoo ?
