Well, both are true, according to the Celebrity Twitter Index released this week by the consumer and brand gurus at JCPR.

Jonny Bentwood — the guru who developed the methodology — has all the details while David Brain has the context and perspective.

But what really struck me about the index is the powerful way that it illustrates just how far Twitter has come in just the past few months. At the same time, it shows how the UK in general and London in particular have really embraced Twitter, even more than the U.S.

JCPR will be updating the index in a regular basis over the coming months to identify emerging influencers and keep an eye on the pulse of Twitter. And if I know my colleagues, I suspect we might see further Twitter index analysis in the coming weeks that looks more specifically at other subjects. I wonder how Downing Street stacks up against other political Twitterers? Maybe we’ll get the chance to find out.

Across the media industry, acquisitions are always fraught with anxiety, and successful join-ups are, at best, infrequent.

But since the very first moment the Spookies arrived, every minute has been a pleasure. They’ve brought an element of fun and a culture creativity which has infected the whole of the London business.

At the same time, the arrival of Spook cemented digital’s place at the core of our London business and really brought digital to life for everyone at Edelman. Their creative and technical expertise paired with our existing digital team’s understanding of social media and digital communications strategy has yielded a combined force that is truly greater than the sum of its parts.

The results speak for themselves: A successful, integrated campaign for Wonderbra that took off just a few weeks after Spook’s arrival; a new online campaign for Krispy Kreme that includes both a hot new website and an effort to engage and build relationships with Kripsy’s countless fans online; and a great programme for the Manchester City football club that provides fans a forum for submitting and discussing their first game day experience, with selected stories being posted around the concourse of the stadium and driving local PR.

Robert has written that our business has been remarkably successful, despite these challenging times. It’s not overstating it to suggest that the arrival of Spook has played a tremendous role in that success.

You see, much of the seafood that we buy everyday in restaurants and grocery stores is overfished to the point that some species may never recover. It was an issue that I had a growing interest in, and the little guide, printed as part of the Aquarium’s Seafood Watch program, was an essential memory aid about what seafood was sustainable.

Time passed. My colleague and I went our separate ways. I moved to London. She went to work for Discovery Communications.

And yesterday, she sent me an e-mail with a link to this: It’s a Consumer Guide to Overfishing that she wrote and published.

Now, I have no idea how many people visit discovery.com. (Quantcast says it gets 6.7 million visitors and 52 million page views per month.) And even less idea how many will see my friend’s excellent page. Certainly it will be more than a few. Hopefully, some of those who visit the page will change their behavior as a result.

But it’s so exciting to see how small interactions can have big impacts thanks to word of mouth and the potent platform that the Internet provides.

Honestly, I don’t really remember the conversation (though I still carry the guide in my wallet), but my friend did. Full credit to her for remembering the chat, and then having the creativity and the passion to do something about it.

What’s the takeaway? Value every interaction. You never know which one will really make a difference.

And BTW, if you want a copy of my little card for yourself, the 2009 edition has just been released.
