Buy Zarrella’s Hierarchy of Contagiousness Today

My book is up for sale now! You can buy either the Kindle version or the hardcover. There are also bulk 5 and 52 copy packs. Either way, go grab a copy now.

The book is based on the years of research I conducted into contagious ideas and how to engineer them. It grew out of my flagship presentation: “The Science of Social Media” which I just delivered as a Guinness World Record setting largest webinar ever.

It’s a quick read and has lots of graphs and real data to help you combat the unicorns and rainbows of bad social media marketing myth.

So go check it out and let me know what you think!

And, if you like any of my work, or my wife Alison’s work, vote for our SXSW panel too!

Introducing a New Tool: WhoReTweetedMe

In preperation for my upcoming webinar, The Science of Social Media (register now!), I’ve developed a new tool:

Simply enter the URL of a recent (between 1 day and 2 weeks old) blog post, click the button and wait a moment. You’ll see a report containing the timeline of Tweets to that URL, statistics about potential reach and average follower count of retweeters as well as a list of the 20 most influential users to tweet the link.

There’s also a bookmarklet you can drag to your bookmarks bar. Navigate to the page you want to analyze and click on the bookmark to see the report.

The tool is still very beta, so don’t be surprised if you see some errors, but I think it’s valuable enough to release now.

Let me know what you think.
