I was hoping someone could find a link to the previous diary about this so I didn't have to type everything all over again.  Migeru often does that when the topic of one diary has already been discussed in depth in a previous one.  It's good for reference.  But Google isn't turning it up for me, and I don't remember the name of the diary.

All that said, I do think the points made in that discussion are valuable and would prove a lot of information for the diarist here.

It's really not a terribly uncommon phenomenon here Fran.  We can't assume everyone has read everything already posted.  Instead of your rhetorical question you could be helping me locate the previous diary.
