Everlater is an application that allows you to create your own travel journal and travel blog.
As you add entries to your everlater travel blog they are also added to a Google Map of your journey. The map includes markers for each journal entry and all the markers are connected by polylines to show the progression of your trip.
Everlater has an iPhone app which allows you to update your travel blog whilst you are on your travels. Your travel blog can include photos of your trip and you can also connect your everlater account to a Facebook account so that all your entries are also posted to your Facebook wall.
