Thanks esrauch - agreed, they're just there for security at present, but have a lot of potential to be a lot more with just a few tweaks to existing functionality. One of the big differences of having circles which could be used as tags is these posts could also be shown to public and not to those in your circles other than those who've subscribed to the tag. I believe one reason Twitter's so popular is it allows you to post whatever you like and people choose to be interested - if someone tried to make the facebook status public and put the same stuff in there that they put on twitter lots of their friends would end up blocking them.
