I, personally, am a big fan of virtual caches. I also am not a convert to Waymarking. As has been mentioned, Waymarking isn't as thrilling as Geocaching. Even with a virtual, I feel as though I have accomplished something once it has been found. I miss them.
I have a proposal for the Groundspeak gurus:
Bring back Virtuals. And keep them in Waymarking. Make them the "crossover" species, if you will; anyone who logs a virtual gains a "find" on both systems (providing he or she has registered thereon). Allow vitual caches to be started on either site and carried over the the other. This might lure some of us to "check out" Waymarking; otherwise, I am just not interested. Entice me!
