One of the latest meme running around are Frappr maps. Frappr is a free service (add based) which allows you to set a pin on a Google map and show off where you are.

You can either add yourself manually each time you want to, but there is a benefit in registering a user (free) because then it is very easy to add yourself to many maps, change comments you previously made and keep track of the maps you want to.

Many podcasters use this to get a feeling from where their listeners are coming and I started Blogher map because I am curious to see where you are from. :)

Do you have a Frappr map of one of your projects too? Put a link to it in the comments!
