Today I was behind my computer when I received tweets about a severe vulnerability in Microsoft Office Web Components. Although it did not apply to me ( I am not using internet explorer, actually most of the time I am not even using windows ), I figured I had loved this way of information exchange when I was a network/system administrator in a previous job.
In a fairly big network it would have been plausible that every few hours a PC would be infected due to this vulnerability. So the faster the problem is known, the less damage could have been done to the client machines.
I can recommend any system/network administrator to sign-up for a twitter account and follow some security related persons / groups. Reading tweets costs time, but it will spare you time when something bad is on the loose.

Very good suggestion. Are there any groups/persons you would recomend as a starting point?
Yes, you could as a starting point follow twitter.com/sans_isc and sans_isc_fast, vcuinfosec has some interesting articles, ubuntusecurity ( if you are using ubuntu ) and twitter.com/security.
Some soft- and hardware vendors have a twitter account to, so you might google around for relevant twitter accounts. Some guys have put lists of twitter accounts of employees on the internet, for example this one (http://webkitchen.be/2009/02/18/adobe-on-twitter/) of adobe employees.
