If you are interested in radio/security, I could see it being an on-going thing. Myself, I rarely uploaded to WiGLE (just used it to peruse regions that were "unmapped") - but, these were also back in the "before-times" when ubiquitous cell network data connectivity was expensive - so, I did my mapping using an offline version of Microsoft MapPoint with NetStumbler on my laptop in combination with a VBScript interface I wrote that would drive MapPoint and visually display findings.

After posting this yesterday - I checked WiGLE for my home and office wifi networks - which have been around with the same SSID for 5+ years and they are not listed, so not many people are actively wardriving these days.

But - like any hobby, there are always a few people in the "long-tail".
