Is there a way? Or can there be a way to publicly mark an address as someone's house or my house? So someone knows I'm at my house or elsewhere instead of just a random address?

If I feel comfortable telling BrightKite where I live or work, then the next time I check in, could it just be from from 'Home' or 'Work'? Wouldn't that be pretty easy to map to my stored 'home' or 'work' (or whatever) location, so I don't always have to put in the full street address?

Unless I'm misunderstanding the point of this service... but, I won't always be checking in from a bright, shiny new place. (Is the point more to 'geo-twittr + photo' where I am, or to 'yelp' about new places?) Much of the time, I'm at 'Home' or 'Work.' (Or on my bike. ;)

I have two ideas for you're already awesome service:) 1. It would be great to have a "check-out" option. When I leave a place, I may not get to the next location for a while, and I'd like folks to know that I'm not at the last location anymore. 2. I would like to have an additional level of privacy for my home address. Basically, if I could just have home address be set to always private, but still say "home" that would be awesome.
