So, mostly to see if I could do it, I came up with this map based on the zip codes people have provided in their profiles:
EDIT: you need to be logged in before you can view the map.
My question is, should this be something for the world to see? I went ahead and labeled all the pins with the username from this site. There are possible privacy concerns here--though a zip code and a user name isn't much to go on. Anyway, I was thinking I'd post it up in forum for comment. I can take it down, or drop out the names, if anyone is concerned about this. Thoughts?

You have a valid point concerning privacy. If we only allow members, I don’t have a problem. Heck, in the pop-up, you can put my photo next to my username! C'Mon you know you wanna. BTW: The IRS already has my address and the creditors have my home phone number. I keep telling them my cards don’t’ work, they are full. Why won’t they send me a new one? HA! So, I’m agreeing with Steve, aaahh, I mean, “SeveNYC“. - Jamie
