Have you a desire to contribute charitably? Need inbound linking to your real estate website pages? Have a hobby, story, bio, or other to broadcast? Enter Squidoo. We've been involved with Squidoo for a few years now and have over 225 lenses, not only real estate related, but the children have done a few of their own. What we like the most about Squidoo is the ability to create something we need for business (or for a child's school project, interest) and donate the earnings to charity. Below is our current month's distribution of monies we earned and where the money is headed towards. A screenshot of our Squidoo dashboard:

The above earnings are from Squidoo's matching of Google's adsense. In other words, the monies above are not from affiliate sales, but from creating lenses (essentially, Squidoo webpages). We haven't gotten into the affiliate marketing thing much, but a friend is making as much $1000. per month on a single lens! If real estate sales are low, perhaps Squidoo may be an option for some to pay a few bills!
