Last November we put up a guide to the most popular Twitter clients. For that post we looked at a random sample of 717 tweets from a handful of heavy Twitter users and identified 19 different ways people interacted with the service. Twitter has one of the fastest growing application ecosystems of any web service outside of Facebook. For this post, we looked at 37,248 tweets and found 142 different ways in which people interact with the Twitter service. Some of the results, which follow below, were rather surprising.
We used the Twitter API to monitor the public feed and capture data on 37,248 tweets over a 24 hour period. We had usable data after about 2 hours, but wanted to let the program run overnight to remove any geographic biases due to timezones. It is interesting to note, though, that the top ten results basically didn't change after the first couple of hours -- though a couple of services swapped positions. That suggests that for the most part, people probably interact with Twitter in the same methods on either end of the globe.
Because we ran our script on a shared host, we limited our script to running at 60 second intervals and grabbed the 20 tweets listed in the public feed every 60 seconds. Since there many have been more than 20 tweets each minute we probably missed a handful of them (if there were less than 20, we only grabbed the new ones). Even so, our 37k is enough data to draw conclusions from.
The script that we used to do this was created for us by developer Kelli Shaver, who also compiled the data for the PDF report linked to later in this post.
Let's get right down to it. One trend that carried over from our November sampling, was that the web continues to be the #1 way in which people post to Twitter. It accounted for 56% of all tweets that we recorded. IM and txt (SMS message), which were also popular in November, remained popular, accounting for 8% and 5% of all tweets respectively.
But that's where the similarities end. Twitterific, which once ruled Twitter alone as the most popular 3rd party client, suddenly has company at the top. Twhirl now serves slightly more tweets than Twitterific, though both account for about 7% of the total. Snitter, which we found served 4% of tweets last November, has fallen out of favor and is now just the 15th most popular method of interacting with the service; it accounts for less than 1% of the tweets we recorded.
Below is the a list of the top 20 ways we saw people tweet and a graph showing the Twittersphere share of the top 10 post methods:
