Just for the record:
I do NOT like the concept of challenges (at least how they are implemented now). My biggest concern is, that the challenges are NOT verifiable. In addition there is no GPS relation. \
I would have appreciated if Groundspeak would have concentrated their efforts on improving the geocaching experience instead of implementing (with a lot of effort, I assume) a disputed feature.
I still do not have an iPad app. I would love to see ways of improving the Geocache quality (there are some suggestions with this). I would love to have badges, etc... Now I get Challenges :-(
I will try to keep my finds statistic clean and from now on I will add "Challenge FREE statistic!" as a headline to my public profile.
Just my two cents....
