It would if we are to stay stuck in our niche, but you need to remember - 
security is about niches, we are all experts -- but in very specific 
fields.

These past 2 years we faced multiple targeted attacks with previously 
unknown vulnerabilities. We experience MASSIVE exploitation of users with 
0days used on web sites and ine mail, etc.

As an industry, as professionals, it is time to get our act together on 
the basics.

I am operations manager for ZERT, and for me, this is indeed at the very 
heart of the matter. How you define this silliness is directly linked to 
how you do two of the most essential parts of security:

1. Vulnerability disclosure - for researchers.

2. Incident response - for.. responders.

If a vulnerabiliy is fully disclosed, unpatched, being actively exploited, 
etc. caused real confusion, and non of us, or any of the written material, 
can agree on the basics.

It's not about fighting on what 0day means as much as it is about how we 
as an industry, a community, conduct ourselves and can reach a common 
language, which directly impacts operations.

So, if WMF was disclosed today after being actively exploited itw for a 
while, what would you call it? How would you respond to it? How long would 
it stay unpatched and when will you realize its importance?
