I'm a big fan of Squidoo, but you could do better with Adsense at the likes of Hubpages. The most a person was getting this payout for one lens for the whole month was $4.12.
I did earned $5.xx from it in last month on this lens of mine http://www.squidoo.com/domains_forums/ Moreover It is also sending me Traffic so it is all win-win situation.
