I wonder if there are any other tools out there that are capable of mining valuable data (for the personal user) from the "Download my Facebook" .zip file dump .. it seems like this is a data format that is ripe for exploitation by other apps/services in the effort of freeing Facebooks' grip over peoples faces. Has anyone looked into the data that Facebook provide, to see what potential apps/services could be built on it? It seems really ripe for exploitation, to me .. but I have yet to download the .zip and inspect its contents. Off to do that now...
