Woo! It took just 252 days for Quizlet to reach the 50,000 users. I couldn’t be happier with the road Quizlet has taken up to here, and I’m glad to share this moment with all of you!

Thanks to everyone who has told their friends and colleagues about Quizlet. I couldn’t have done it without you!

But before I dive in I’d like to thank everyone for the huge flow of ideas coming in through the blog and the feedback box. It’s a little overwhelming, but I think some genuinely good features have been suggested. As always, development is continuing at break-neck pace.

——————

Today marks the 500th day of Quizlet’s existence. That’s a long time! Sometimes I can’t believe it myself, that I’ve been working on it so long and stuck to it. Of course, 455 of those days were private testing and idea-developing times. The site has only been available to the world for the past 45 days, so all new registrations have been since then.

Speaking of registrations, user signups are continuing to come in at a breakneck pace. On average, it’s about 150 people per day, so as I’m writing the sentence there are 8,533 registered users. If the trend continues, about five more should show up by the time I’m done with this post.

Interestingly, the number of sets created per day has recently surpassed the number of users per day. For example, today we had 185 sets created in the last twenty-four hours. Impressive! I think as the user base grows, older members are moving on to create their second and third sets, while first-timers are still a big portion of the new sets posted.

Here is a graph of the number of users against user age on Quizlet:

The big spike is at age 16, right around sophomore/junior year in high school. It’s interesting to see how this data has changed since I last graphed the ages of Quizlet users. Since the last graph, the college students have definitely been picking up Quizlet more.

The average user answers 61.7% of all the Learn page prompts correctly. That seems decent, but I’m working on ways to improve that average (as in, having people answer correctly more often).

Unfortunately, Internet Explorer has passed up Firefox as the most-used browser on Quizlet, with 52% of all users. Next comes Firefox at 37% and Safari at 7.5%. That’s not too bad, considering internet-wide averages put Internet Explorer at . For more on why I’m complaining about Explorer, see this post I wrote about a bug in Quizlet.

All “Set” pages collectively account for about 40% of all traffic on Quizlet, then the Test, Group, and Learn pages take up another collective 40%. The Scatter page is a little further down the list, but it has by far the most repeated visits, as expected.

Geographically, the citizens of San Diego consistently comes in as the top users of Quizlet:

.

This is just a graph of the last 500 visits on Quizlet, so it’s not completely representative of all traffic. Still, It’s definitely fascinating to see the big community in San Diego and the UK, as well as the large spread on the East Coast and Midwest.

Some quick averages: Mr. Average user has created 0.8 sets, posted 4.3 discussion messages, logged 62.9 scores on the Learn Page, and entered 30.3 terms into Quizlet.

Well that’s all I have for now.

Until next time,

Also, 2,200 private messages have been sent since their introduction 13 days ago. Yowsa.

I think I’m becoming a stats junkie. I also think that despite my best efforts, I’ve created a bonafide social network. Well, that probably isn’t so bad. Just don’t come asking me for profile pics. The answer is no!

Lastly, I’ll leave you with a screenshot of the new Scatter game, which I’ve managed to “widgetize”, and so it will be embeddable in your own blogs and whatnot. I have a whole bunch of tasty new features coming up on Quizlet in its next update, but I’ve decided I shouldn’t keep listing them all in case I don’t manage to make them all. Here she is, embedded in a local copy of a site I made once.

Also near the top of the list, is Jefferson City → Missouri. I guess we can call that the least well-known of the US State Capitals. Sorry, Jefferson City.

The award for the most used set on Quizlet goes to Reprise Ch. 23 – Relative Clauses. Second place goes to the previously mentioned US State Capitals list.

Sixteen is the most common age among Quizlet users, with 387 users. Runners up are 15-year-olds, 17-year-olds, and 26-year-olds. This data is from the birth year entered when users sign up.

The user with the most terms entered is suresh, who has imported some very large word lists. He comes in at 11,034 terms.

I may only have entered 3,118 terms, but no one is touching my 68 created sets.

Finally, one last statistic that consistently blows me away is that even though I created Quizlet, I’m not its biggest user. That honor goes to my good friend KevinFace.

Well that was fun. Perhaps I’ll make this a regular thing State of The Quizlet item. Let me know if there’s any other interesting data you think would be cool to find.
