I feel that many collectors did participate. My own experience with "sharing" is many congratulatory emails. Unfortunately , there also were many "I'll trade you" . "I'll buy it from you." "What do you mean your not interested." "My eight year old would really like this one." And then there were the " #$%^ you." " Keep the #$@^%* thing. " "Thanks for nothing."
I'm a nice guy but I really don't need the abuse.
