Blahtest!

When you post something with Google+ mobile, it comes up with a screen that shows your location, a vague, general and broad location.  

You can remove the location, or select it to get some choices of more specific addresses and businesses.

In NW Portland today, I got the initial location shown in this screen shot.  Just a couple blocks away, it worked fine.  But at this one corner, NW 18th and Lovejoy, it always placed at in "blahtest, Portland, Oregon".

Awesome!
