A (rather peevish, I admit) question: after GO's lengthy exposition of BCF
last week I replied at even more interminable length with a number of (I
thought) critical points, as well as a few short messages. The short ones
appear to have been picked up on, but my longer comments appear to have
produced a deathly silence. I assume from this that:
a. I have stunned George into contrite silence; and/or
b. My comments were so idiotic as not to be worth replying to; and/or
c. I have bored everyone into a state of catatonia.
However, if anyone out there is still awake, I would be curious to know just
how nonsensical or uncomprehending my message was. Thanks.
