Proving again that your tech is only as good as your data, your UI and your adaptive programming, WIRED does a story on bad online maps. These things have their place, but yes--I constantly get nonsensical directions out of them. Then again, if I used a paper map and used it without common sense, I wouldn't even be able to open it--those things are complicated to unfold!
My point is that the tech is only OK--and opening it up so that it is the most useful for everyone does not involve making the system do everything. It has to do a few things clearly and intuitively.
