I'm working on a proof of concept alumni site with a WordPress backend. I want to have a very simple map that shows where alumni are living. I'm thinking something like the Bing API or a simple open source solution - points on a map right now. Not sure yet how I will be getting locations, perhaps a user submission system somehow. Any ideas on good, solid, simple ways to accomplish something like this? I'm on a LAMP stack hosted with WebFaction, and I know just enough PHP to be dangerous.
EDIT: Here's what I ended up with. Jlivni got me looking the Google route and some hacking on this method gave me this:
It's powered on the back end by a publicly viewable Google Spreadsheet. Pretty easy to implement and hack up. And I can pass of the editing of the spreadsheet to just about anyone and they can carry out that task.
