I didn't see what was wrong with Locationless, Webcam and Virtual caches ever - Groundspeak just made Waymarking, it seems to me, so that they could run a game they could call theirs - they didn't come up with Geocaching, so they wanted an original idea, which never took off. I bet more virtual caches have been logged on GC.com than Waymarks in all time  - take Bear and Ragged's Waymarks on Dovers Hill - 4 years old, and not even one log 

The whole point that they still can't be viewed like Locationless caches, is that they created a SEPARATE AREA for them - when you log a challenge (although it did originally) it doesn't add to your total count. It wasn't a cache type. It had a whole tab for itself, a whole page, a whole map! THIS was where Groundspeak went wrong - if they had made a "Challenge" a cache type, we wouldn't be saying RIP to them - we'd be logging them, and creating them. 

When will they learn
