I am learning some of the behaviours of Community Polls and the Facebook Comments feature. Looks very cool.

Pardon as this is a dumb question but... where are the comments stored? On Facebook, in a user's account? Because I see the Facebook Avatar show up, it appears to be connecting with, communicating with Facebook. But when I go into the FB account I do not see the comments stacking up.

Can anyone give a quick explanation on where these Facebook Comments are going, are being stored?
