Tonight I wanted to get a feel for how much of the United States is covered with profiles from agents like you. So, I took the data in the database and worked with the Google Maps API (Application Programming Interface). It gave me a nice representation of which areas the agents are covering, and I thought I'd share it. Take a look at http://www.pinpointagent.com/maps/getzips_v1.cgi and definitely drop by the main site at www.PinpointAgent.com to list your profile free for six months.
I want to work on a "coverage area" next, with nice intersecting circles to show where agents cover. I had fun customizing the PinpointAgent logo for this - so I didn't have to use the standard Google "marker". Double click to zoom in, click on a logo to bring up that agent's zip code (I could also link to an agent profile in a separate window or even display names, photos, etc in that "info window" - but i'm still deciding what to do with this).
If you find this interesting, and you want to talk about it, let me know - I can go into some detail and we can certainly help with these kinds of projects.
If you had this technology in your hands, what would you map? Your own listings on your website? Maybe local relocation companies (moving companies, grocery stores, fire stations, schools, etc)? Maybe both "mashed up" into the same map to show how close your homes are to local services?
