I will also point out that the SoWaller to whom you refer, spent more than 40 hours after Hurricane Ivan passed through, taking photos of people's homes and posting them on SoWal.com so that the homeowners could feel more comfortable knowing the condition of their home, without having to hire someone to check on the homes for them. Add to that, the time that it took to take accurate notes on home condition, and reducing the image size of the photos, plus the time to upload them, and you will get more than 700 hours. Though, I can tell you that your average post time of two minutes is too long. I'm a fast typist. ;-)
By the way, I'm not a Realtor who tries to gain everyone's business. I want to keep my number of listings small, and be able to give excellent customer service to each of my customers. I think that is much more difficult when you have too many listings.
