Nice idea for GeoTagging. However, lacks maps when zooming into large green landscape of London? The vidcast looked easy, but my photos were on top of each other and the timeline. Not obvious how to separate it out without text data and map.
The one feature I looked forward to was to match a photo with a known local time with my GPS data. I just could not determine where or when it fit into the timeline or location.
It may work for you, but this would be better as a beta. Let's hope for v2 or v3.
