I love seeing CMs answering in threads or taking part in fun threads like "What did you do in Planet Zoo today?". Commenting pn builds, maybe give advices that kind of stuff, when they find the time. Because that would mean interacting with the community. I would also love to see them address bugs more, so that we know what / what is not being looked into currently etc.
But commenting on animal wishlists would, as
@jcp011c stated perfectly, be seen as "hints" or simly biased. We once had a forum member who, for whatever reason, thought the Devs would be "dog people" and only give "dog people" what they want. It was abstruse to say the least. Now imagening a CM actually support animals by their personal preference... oh dear.
I'll give an example. If I were a CM, I would probably applaud animal wishlists with more otter species, cats, canines and monkeys a lot, but birds and fish... eh, not so much. I'm just not fond of birds. But because I were a CM, players would absolutely call me a witch and be sure, that I, a CM with no power over development whatsoever, would be the reasonst we do not get flying birds yet.
