No worries, Dana. Good to know you do read them. And while I see your point -- it is a public forum, of course -- I feel there's more normal human communication going on here. It's the only forum I've ever participated in, and that's the reason. Other forums feel like they increase isolation. The odd time I've tried posting on others, and my words just hang there in cyberspace. It's an empty form of communication for me. Angie's forum, on the other hand, feels like a big group conversation. It's more fun.
The buttons help solve the "I don't have time" problem. They are a quick way of showing that I appreciate the feedback, even if I can't respond to everyone individually.
And I do click on your posts sometimes (like this time) because you ask interesting questions. Also, your occasional feedback on my threads tends to be intelligent and concise -- qualities I respect.
