Hi, I have found a bug in Hermes 0.2.2 - once you successfully pair Hermes with Facebook account it is not possible to switch to another account. I have found a workaround though .. tough one.

To get rid of facebook account settings you need to change the file /var/lib/gconf/apps/maemo/hermes/%gconf.xml - either delete the secrets stored there or delete the file (that will get rid of twitter settings too). Then the gconf daemon has to be restarted to get rid of the in memory loaded settings. I have just restarted the tablet since I don't know the command to do that. Then Hermes could be run again. (I uninstalled the Hermes app before the restart but I think it migh not be needed to do).

hope it helps
