This is a page (best for iphones) for sending your current location to someone via email. The motivation is this: Instead of verbally describing where you are when you want to meet someone, why not send them a link to your location. This way they can click the link, and (if they have an iphone) simply click directions to that location.
To use it navigate to jeffpalm.com/findme/ and you'll see a screen like so:
Then your can either goto the location, mail it, or read about this page. The link you send or view (on an iphone) will bring up a screen like this:
From here, you can click the blue dot to find directions to this location.
