Tweak to Visibility of a Shizzow Account

kudos on the re-ablement of the gtalk im feed
I find the messages in it very useful and it is interesting to follow the 'story' they tell.

was curious if anyone else would find it useful to have an intermediate 'Visibility' setting for a Shizzow account.
"Allow all my messages to be public but only share my geo data with my friends"
Or even change the Shizzow policy to state that all messages are public unless you have a private account (like twitter).

might be interesting to 'listen' to all the conversations on shizzow, and then get the addtion of geodata for your friends
