Concerns have recently been voiced about Twitter’s user base: churn is over 90%, and the average number of tweets sent by a Twitter user is, er, 1.
Twitter, however, is undaunted by such stats, and, instead, promotes the fact that its monthly number of tweets continues to climb ever higher:
But what is the value of a tweet? Metrics I’ve seen range from a couple of cents to a few fractions of a cent. Is Twitter selecting the data that presents it in the best possible light, while ignoring the fact that its astronomic growth rate may have peaked? And how many of the tweets in the above graph are result of spam bots?
Now that Facebook, and, more recently, Google, have gotten into the realtime microblog scene, expect to see Twitter’s user base numbers continue to erode in the months ahead.
