I had a great pin trading time during my trip in May. It was so nice to see some legitimate, new, non-scrapper pins on boards and on CM's lanyards. The CMs also seemed happy to have the lanyards back - since this is recent, I'm not too sure how long this enthusiasm will last. When pin trading in the past with CMs with lanyards, when there were also very few pin boards, many times it would seem to be an inconvenience to ask one to trade.
I completely understand this perspective as these are people being asked to engage in trading IN ADDITION to performing their normal jobs (although I'm always respectful to only ask those CMs who seem available to trade and not in the middle of a job-related task).
I much prefer the pin boards where I can be only slightly annoying in asking to access it (if it's behind a desk) and make my 2 trades without bothering anyone. I know that the reason to engage the CMs in the process is probably Disney's way of enhancing the guest experience (and maybe policing people who can't play nice and follow pin-trading rules) but I can't help but feel I'm in the way of them doing their actual job and I always feel the need to make small talk, despite being an introverted person.
I had an amazing trading experience with a CM near Space Ship Earth who had a lanyard with amazing pins to trade but made everyone answer Disney trivia to earn the best pins. I made sure to send in a note saying he really went above and beyond to make our interaction special!
