As I write this, I’ve tweeted close to 39,000 times. But according to one report, a large chunk of you have never sent a single tweet.

As reported by the Wall Street Journal, Twitter analytics company Twopcharts says that, according to its data, 44 percent of Twitter accounts have never tweeted. No “Trying out this Twitter thing.” No “Just setting up my tweetz.” Not even “Hi.” The Journal places Twitter’s userbase at 974 million accounts, so if you do the math, that’s roughly 429 million accounts that have been silent.

What are all those users doing? Some are likely just readers, others may have created an account, only to forget that it exists; still others may be in the “I don’t get Twitter what is this I don’t even” camp.

That’s a whole lot of silence.

Of course, just because an account has sent a tweet doesn’t mean it’s heavily used: Twopcharts’ data indicates that 30 percent of accounts have sent between one and ten tweets, and that only 13 percent of accounts have at least 100 tweets.

That’s a whole lot of silence.

Granted, these numbers are very unofficial: Twitter has not commented on them, though according to TheNextWeb, Twitter had 241 million active users in the last quarter of 2013. Still, for a social network that relies heavily on a high volume of user engagenemt to sell ads against, such a high number of quiet accounts is perhaps not ideal.

If a lot of those tweetless users are just reading, though, you have to wonder if Twitter will make more design changes with passive tweet-readers in mind.
