Looks pretty great so far, and I really like the pages you're creating.
Just a handful of things:
1. I don't like logging in with my Google Account. I can see that you're using my Google pictures so you're going to need that. I don't like it anyway.
2. I completely don't understand the graph at the left hand side of your pages. Perhaps it's number of photos (but then that info appears twice, right?). Or is it text written? Or is it distance covered? Or is it coolness of the segment? Some information would be nice.
3. Or even better, how about customizing that area? I know you're quite early in development, but I'd expect to see some interaction there.
4. The location was a little off when I loaded my non-geotagged pictures. It placed them somewhere in Slovakia for some reason. After placing one of my segments into Africa, the overall location marker moved to Germany.
5. These little info boxes are cool. Can I do them myself, please?
6. The time line is interesting, but I'd like to customize that a bit better. In my case, there's lots of empty space at the top and the bottom because I arrived on Saturday and left on Tuesday, causing empty weeks there.
Ok, that was a bit of stuff. Don't take is as criticism, I really like the concept, but I'd also like to see it developed a bit more.
