As probably many of you, I've long been an avid follower of OkTrendscache, OkCupid's blog. After a three year long silence, finally some new articles appeared, and it soon became clear why: Christian Rudder had been working on a book, Dataclysmcache.
It contains tons of interesting findings extracted from the copious amounts of data available to todays datascientists, but I wanted to show a short excerpt I found quite striking:

Later in the book you'll see that they actually message women more consistent with their own age (up to ten years younger), but I still found these two graphs very interesting (data is from ratings of OkCupid users, graphs are copied from the book).
Finally, for all of us online dating users:
Or, in other words: Very short messages - a single tweet - are actually more successful. Now this is across all users and might not hold true if you only consider more educated users, but still. (I wish I could run some of my own analysis on OkCupid data!)
