I've made some additional updates, mostly in the personal data views on the data. You can now link directly to a specific visit of yours (not really sure it is useful, but who knows) and it will include your notes on the visit as well as the UNESCO data. You can also share that link quickly via Twitter/FaceBook/Google+1 through the buttons in the top right corner of the page. It is nearly identical to the Site Details view but more personalized.

I've also updated the Sites Near Airport page so that it returns a text-based list in addition to the map so that users on mobile devices that don't support GMaps can have the same fun on the go. That would've been useful to me this past month.
