Now here is an interesting concept. A neighborhood social network. They are on a mission to "improve quality of life in America while building the next generation internet company."

I was recently walking my dog down my street towards the park which I have done on numerous occasions. But this time, I ran into a neighbor I have never spoken to. We got to speaking about investing in real estate and to my surprise it turned out he is an active real estate investor with over 40 residential properties under his belt. I told him about Rent Marketer and he was very excited to post his vacant properties with us.

Now, I have lived in my recent house for over 2 years and never knew of this gentleman. How amazing would it have been if I could go to one place online and view and meet my neighbors.

FatDoor is going to be this place.  Here are some more ways the social network could work. From fatdoors blog and an article from Paul Lamb on CNET:

Here is an excerpt from the article:

What would a world look like where the best of social-networking tools were put to use in "average" communities and for the larger social good?

It might include:

- Neighborhood social networking. While sitting at home using my PC or driving around my neighborhood with my cell phone, I can identify and connect with people on my street who share common interests. Neighbors I may not know have a choice to make their profile available to me and others in our immediate neighborhood. If an elderly neighbor needs help moving furniture, I can find out about it on our neighborhood social network and volunteer to lend a hand.

- Educational social networking. Students, teachers and the community at large participate in school-based systems that match school assignments, activities or needs with individuals inside and outside the school who can help.

- Social services networking. Using a cheap wireless device, an abused spouse or a person recently released from prison can be linked immediately to a variety of services in their area, including temporary housing, counseling and employment support. Before they even show up at a social service agency, they could access information about the best person to talk to (based on reviews from other clients) and know what services are available in real time without having to wait or be told to go somewhere else.

- Street-smart social networking. Rather than handing over a quarter, a passerby can assist a homeless person using a one-click system that identifies local services or electronically transfers money to an account at a local grocery store or restaurant.
