I can't believe I never saw this post before now. Of course I definitely had noticed Baldur's absence, so he is wrong in thinking no one would care. I do think that JBSNBSN99 told me in person the last time I saw him in Dallas that Baldur's interest in zoos had waned.
I also perfectly understand how ZooChat (or any other forum) can become obsessive and waste time we should be using more productively. (At least I can say I am not on Facebook and I do not own a television).
Anyway, sorry to see Baldur go but I perfectly understand.
