Quoted from robin:
I will look into that as well. It has been mentioned before and I think a flag for removal button could fix that.
Robin, this is a great idea. Once implemented, each of us should take on the task of keeping our own city updated. This could easily become a very powerful tool to find machines when traveling. In the current state, it has too many errors, inaccuracies, and incomplete information.
BTW, I agree with the decision to get rid of "karma." I'd probably keep thumbs up and down, though.
Have you given any more thought to reworking the ranking system? At one point, there was some talk about basing it upon position on our lists of relative rankings. For the record, I greatly prefer this idea. I also bet the amount of rankings would explode. The current system takes way too much time.
