Government Executive reports on a growing movement for transparency in government, particularly in the field of government expenditures. As I commented there, I like it, mostly. EWG has done it to farmers for 12 years and they've mostly survived the experience.
Have I mentioned David Brin's Transparent Society recently? I like it.
I'd extend the idea to many areas. For example, Down to Earth has a post about McNuggets--how McDonald's has some housewives looking at their processes. Why shouldn't McDonalds stick video cameras hooked to the Internet in the places they want us to see, and the places we want to see (as mentioned in the post). Granted, very few people would ever want to watch 50,000 birds eating and sleeping, but PETA might check now and again.
If people can use cameras to watch pregnant cows and babysitters and somewhat senile oldsters, we can use them elsewhere.
