Here lately, all I see is spam on my Facebook wall. The most popular? Probably "See a girl have an orgasm while riding a rollercoaster". I have a hard time believing that 20-30 of my friends clicked the link, but then again, you never know. Either way, I think the most important word in advertising today is relevancy. It's ditching the production model of the past- having an idea, and executing it as soon as possible to capture a relevant audience at a relevant time. This is especially true in digital.

Ed Relf, CCO of Mind Candy says it best:

"I have worked in places where it takes as long to sign off the bugdget as it does to create the campaign. It's a broken model that doesn't work. If I have an idea in the morning, we execute it by the afternoon. It's the only way it can work in the online space."

For all I know, Webroot could've been working on this for months.  Regardless, it's simple, relevant, and smart. 

Still, my advice for not getting a virus?  Go buy a Mac.
