[kwlug-disc] Heartbleed affected sites

Yep, had caught those aspects.

Keyword being 'potential'. Which is only to say, with the media all 
running around with their heads cut off, and only a small subset of such 
services you use WITH impacted servers AND real potential harm to you at 
exposure IF you have an account worth messing around with more lucrative 
than others, there's a lot of FUD out there.

Which is not to say you won't be impacted, nor that it won't hurt when 
you are ... but it's not EVERYWHERE for EVERYTHING.

I don't dispute the problem is discerning when it really matters.

I'm only irritated that they put out carte blanche 'change everything' 
'just in case'. This, my industry (I.T.), should be able to be rather 
more surgical, and less 'there MAY be risk, better safe than sorry'.

Considering the time and expense and potential exposure most everyone is 
being told to expend. Most of which is pointless for lack of real 
exposure. That's my issue - lots of FUD and noise, most of it, just 
noise, and we all have better things to do.
