For much of today, my blog was unaccessible because Media Temple had a far-reaching outage.

After unsuccessfully trying to reach my site, I was made aware of this through Twitter (why no email correspondence?)... with a simple search of "Media Temple", there were endless tweets referencing the outage. This of course speaks to the power of Twitter's instantaneous news stream; but surprisingly, it also spoke to the potential power of Twitter's Promoted Tweets ad system. Media Temple competitor Storm On Demand saw this is a immediate opportunity to reach targeted searchers and acquire new users with a specialized coupon. Smart. And Twitter is the perfect system for this short-lived, real-time marketing opportunity.

Facebook is terrific for reaching hyper-targeted users (demographic, location, taste / preference, etc). And this is an example of Twitter's effectiveness around real-time, event-based advertising.
