I wish I would have replied to this sooner. My reaction to the questions though is...
Wow! That is a lot of questions! If I were going to discuss them, I'd really like to see what you say about them first in order to see where you are coming from with each one.
If a thread like this took off it would be fascinating though, eh? Realistically I imagine talking with folks would work best though, mostly since there is so much to say about what you listed. If you want to talk with me about any of the stuff you email me at porterm *atsign* oclc.org
That goes for the rest of you too!
