You.
If you didn't think the person had time to read the article that: a)
answered the question and b) informed them how to prevent the problem
in the first place, then why didn't you answer the question in your own
way and then provide the additional information?
The "What was your point?" question was, I think, rhetorical and meant
to be subtle. I'll be blunt.
I can think of only two reasons. a) You didn't know the answer (which
I suspect that you did know) or 2) You are posting unnecessarily in a
thread already answered a quest for more letters after your name.
Now if it is OK with you I drop this little spat or move it offline.
