In what will certainly become a smashing viral success, P Diddy, a relatively newcomer to Twitter (@iamdiddy), educates Ellen DeGeneres (now on Twitter – @theellenshow-  although at Press Time has yet to “tweet”).

In typical Diddy fashion he pronounces himself the most popular man on Twitter [112,820 followers - all #s as of 3/11 @ 5 p.m.] although Shaq: @The_Real_Shaq, [280, 948 followers], Ashton Kutcher @aplusk [290,534 followers], and non-celebrities (although arguably Social Media celebs) such as Pete Cashmore: @mashable [221,189 followers] and Kevin Rose: @kevinrose [263,953 followers - and the guy who got Ashton & Demi to tweet] have more “followers” than he does.

Whether he’s the king of Twitter or not, the trend of celebrities using Twitter as a platform to speak directly to their fans is certainly a viable (and smart) usage of the “tweeting” capabilities. In the same way that brands like Comcast: @comcastcares and Jet Blue @jetblue have communicated effective and important information and solutions to their consumers, strengthening their brand image.  Celebrities can utilize Twitter to clear up rumors, make big announcements, seem more accessible to fans, and ultimately strengthen their brand – which is what is also compelling to us as marketers and branders – the tweeter can now be the driver of their own brand message.

In the clip above Diddy butchers the explanation of Twitter calling it a “mass e-mail” which it certainly resembles, but isn’t. But the fact that he is on Ellen, explaining Twitter, and going out of his way to disclose the ways he utilizes it is what is important.  His excitement about it as a communication tool is the excitement I hope to instill in all of my clients.

I believe that we can officially say that Twitter has gone mainstream.

Note: Although I jab at Diddy’s explanation of Twitter, I find it tough myself to explain it in less than a paragraph. Does anyone have a succinct explanation they use? Do share!
