Well said, Greg.  I agree.

Subject: Re: Wi-Fi security flaw to be fixed in 2007

Stef:

My reply was not intended as a personal attack.  I am very sorry if it 
seemed that way.

My main point is that we need to be conservative in our reactions to 
security bulletins.  I get at least 30 messages a day from security 
mailing lists.  (It used to be closer to 120... I had to pair down my 
subscriptions for sanity.)  If I took every note at face value, I would 
be too afraid to get out of bed in the morning.  Do we need to pay 
attention to these announcements?  Yes.  Should we share information 
that we deem important with our co-workers and clients?  Of course!  Do 
we need to react to every bulletin?  No.

Cordially,
-Greg
