David McCandless used data from Facebook updates to look at when people break up with each other throughout the year.  It looks like people like dating in the winter and being single in the summer – and a lot of people use breakups as an April Fool’s joke.

How to make freemium work

Here are some of the main points Libin covered during his talk:

• Sometimes people say “The best product doesn’t always win”, and are implying that you should focus on other areas, like marketing. In the Internet age, a good product can get the rest of that stuff (marketing, etc.) for free. So focus on that. And then charge for it.
• A year ago Evernote was making most of its money from licensing its technology, but it focused on its premium plans ($5/month or $45/year) because that was more scalable. Now, premium subscriptions bring in around $300-400k a month, and licensing represents around $45k.
• Evernote has 3.1 million cumulative users, and adds around 10k a day. Around 68k paying customers.
• Users have grown more valuable over time. New users convert to premium at a rate of .5%.  But of the users that signed up two years ago and are still active, 20% have become paid customers.
• This trend is important — most users quit quickly. But the ones that stay become much more likely to pay over time.
• Evernote’s cost per user is around 9 cents per active user per month. It makes around 25 cents per user per month. The site reached break even a year and a half ago.
• Entrepreneurs should aim to be making money on each new active user as soon as possible. Otherwise scaling just means you’re losing money faster, rather than earning it
