I understand the limitations of time perfectly. It's one of the reasons I've been so hit or miss in the past with comments. I have had to set aside poetree time for myself, which has turned out to be a lovely thing for me. :)

I do like the idea of encouraging jumpings-in between different threads. Not sure how we can do that, but we'll see if we can figure something out.

I think the discussion questions is a good thing. We're already trying to encourage posters to include a discussion question or two at the bottom of each post. Having a weekly discussion post might be another good way to encourage conversation. Thanks for the idea!
