I’ve previously posted about Tripline, which is an excellent application that students can use for making maps of field trips, historical events, etc.
They’ve now just announced new tools that let you create maps of your Facebook friends. Now, there are a lot of those kinds of apps that I list at The Best Ways To Make A Map Showing Your Facebook Friends (& Twitter Followers). But Tripline’s are unique — not only do they let you make maps of where your friends live, but you can also make maps of their most recent “check-ins” and where they grew up.
You can read all about it at Tripline.
