Topics don't have to be controversial in a Global Village. Responses can be informative--and supported.
It should be OK to do some thinking, and Googling--and respond a day--or a week--later
Responses need to be expressed in paragraphs--not single sentences, a phrase, or (gasp) some string of capital letters.
We should expect and seek multiple POVs.
Comments never need to descend below level 3--and might be better at level one.
We should be here to learn culturally--and to have fun.
It works well in online academics--it could work here.
Threads and comments now are unacceptable--a waste of time.
