Freebase users on Google Maps, a mash-up

Here is my mash-up showing Freebase users on Google Maps:

• You can search by username and fullname. Example “john”.
• MQL regexp is supported. Example “^j*” (all users that start with j)
• Or just show everybody (with a geocode). Example: Everybody

Issues raised:

• Some location data was foobar. Karlsruhe, Germany is shown in Somalia Data fixed
  
• How could I add a user’s image? Done.
  Freebase data-model weirdness? Why is there an empty picture_s field and a /common/image field for a user_profile?
• I have to make two almost identical queries (searching name and my_full_name) because of a lack of an OR construct in MQL. This seems pretty inefficient. Can anybody suggest a better way? Done:Kurt suggested using “/type/reflect” reflection properties (not for the faint of heart!)
• Is there a clean way of being informed when all MJT tasks have completed?

Feedback very welcome.

Update:

• May 9th: Added button navigation and profile photos
• May 11th: Various user interface improvements + Kurt’s solution for a single MQL query.
• Nov 07: Fixed broken links
