The charm of the forum is that it organizes things well and info is there for all time. So anything technical and/or of lasting value would have it’s best home here.
fb, the whole stupid thing, is perfect for posts of zero lasting value. I feel strongly that most of our discussions do indeed have lasting value. I’ve read every post in this forum, all 6-7yrs of them. There’s great stuff in the older posts.
There’s also the issue of auto notification. People who like being notified of every post will like that aspect of fb. People who don’t want to receive emails re. each post and instead just want to hit the website occasionally, will stay away from fb.
I don’t really have a plan or any over-arching vision. People are different and like to do things in different ways. I figured that creating the SpecE30 fb page would be in synch with some folks info preferences. And those of their teenage daughters.
