You can kind of do this by looking at the clock on the pedestrian sign. I would think it would help more with traffic flow than saving on gas.

Gmail isn't self-hosted or open source. He wasn't just saying both are popular. Unless you meant something else?

but people can take offense to anything, so that means you would be responsible for all of the stupid things people get offended about.

People don't have the right to not be offended. I think you are half right, but offense probably has to be both given and taken, not just taken.

You are right in saying that if we don't have better evaluation methods, it doesn't matter too much. The trouble is, should we just ignore the problems with current methods? It seems the equivalent of sticking your fingers in your ears and saying, "la la, I can't hear you."
