I've continued to try Here and Now from home occasionally, and one time, early this morning, the service actually succeeded in determining my location and pulling in data. Unsurprisingly, it had no events, movie theaters, or restaurants to report to me, but it did provide the weather.

Unfortunately, I hadn't run it from the command line, and it returned to the familiar "Location not detected" on subsequent attempts. I'll keep trying though, and eventually I may have success and failure logs to contrast.
