We've just added Gmail/Google Talk to our list of services. So now when you change your status message, it'll show up in your feed. Finally, there's a way for people to comment on each others' inscrutable status messages.
To use this feature, just go to your Settings page and add Gmail/Google Talk. You'll receive a chat request from firstname.lastname@example.org in your chat interface. Click "Yes" and your current status message should show up on your feed almost instantly. Changes to status messages also show up pretty much instantly.
