October 30 2009
One of the most ubiquitous and disruptive websites to emerge in the last 10 years is Craigslist.

Want more clicks? My new data suggests that you should Tweet your links in afternoons, evenings and on weekends. Continuing the study of Twitter clickthrough rates I started last week, I added over 100 more of the most followed Twitter accounts to my database and indexed click data on over 20,000… read moreOctober 26 2009
Earlier this year I read a paper called “Modeling Blog Dynamics” in which they propose a method of modeling the spread of links through the blogosphere using zero-crossing random walks and exploitation vs. exploration applied to a logical flowchart model: The authors suggested that the model could be used in… read moreOctober 21 2009
Tweet Much? Don’t Expect a High CTR. New data I’ve been working on seems to indicate that the more frequently you Tweet links, the fewer clicks you’ll get. I’ve been working towards a statistical model of how an individual makes a decision to ReTweet a specific Tweet and in that process,… read moreTo #SaveReTweets, Make Sure Everyone Knows How to ReTweet
October 19 2009
I wrote a little while ago about how Twitter’s plans to mangle ReTweets with its Project ReTweet, and the danger that poses to the crowd-invented functionality. After having several conversations on the topic and wondering what we could to do save ReTweets, I’ve come to the conclusion that the only… read moreDoes Social Media Accelerate the Spread of Dangerous Ideas?
October 15 2009
Is the social web becoming a dangerous platform for contagious, destructive ideas? As social media usage grows and becomes a hive mind of collective consciousness, it enables a number of positive things to happen, but it also presents a grave danger in the form of dangerous memes. Dan Dennet gave a… read moreOctober 12 2009

Dr. TweetDreams takes those Twitter dream musings and tells you what they mean. DrTweetDreams.com analyzes the elements of your Tweeted dreams to see what they mean for your past,… read moreTwitter’s Deal With Search Engines? I Called That.
October 09 2009
News broke yesterday that Twitter is talking to major search engines (Google and Microsoft) about licensing Twitter’s full firehose API. Over the past few months I’ve been seeing signs leading to exactly this kind of thing; here’s why Google will jump on this data. When Twitter announced their intentions to completely… read moreSeptember 30 2009
When marketers think about “going viral,” they think about creating infectious content and getting it in front of the right people. And while that’s a great place to start, contagious design can also go a long way to help. Here’s 7 things to think about when designing a blog or… read moreThe Science of ReTweets Report
September 24 2009
After putting together the most recent version of my “Science of ReTweets” presentation and putting it up on Slideshare, I got a lot of great feedback, including that it’s a little hard to understand without my explanations along with each slide. So I pulled all the data together (including some… read moreNew TweetPsych Feature: Top Lists

Now that there are over 80,000 users indexed by TweetPsych, I’ve added a new feature that ranks users by specific characteristics. For the select traits listed below, you can see the 20 users who scored the highest. Please remember that this is for entertainment purposes only and that the codes are… read moreThe URL Shorteners that will get you the Most (or Least) ReTweets
August 26 2009
We know that most ReTweets contain a link, but there are hundreds of different URL shortening services available to help you save space with that link. I analyzed my database of over 30 million ReTweets and compared them to over 2 million random Tweets to find which shorteners are the… read moreThe 20 Least ReTweetable Words
August 25 2009
I’ve looked at the 20 words and phrases that tend to get the most ReTweets, but what about the flip-side of that coin? What about the words that are least likely to get your ReTweets? I used my database of over 30 million ReTweets, and compared it to a sample of… read moreAugust 24 2009
140 characters doesn’t leave much room for extraneous letters, numbers or symbols, so you might think that punctuation would be sparse in Tweets. But I compared a random sample of over 1 million “normal” Tweets to a sample of over 10 million ReTweets and found that 85.86% of Tweets contain… read moreAlso find Dan on:
