Last weekend, Joe McKendrick posted a review about my book Entreprenerd on forbes.com: Three Lessons Learned From A Technology Entrepreneur’s Journey: It Takes People, Patience, And Persistence. How did that happen?

Laten we het eens over petten hebben, meer bepaald over mensen die het nodig vinden binnenshuis een pet te dragen, niet alleen thuis, maar ook op school in de klas, op het werk achter een loket, en zo voort.

The book Entreprenerd was released on May 15 and when I look at the registered sales, I see that only 98 copies were sold to date. I know that this is an underestimation because some people have told me that they bought the hardcover, and those sales aren't visible in the reports my sales channels made available to me. Nevertheless, I am somewhat disappointed. I thought the book would be more popular. Maybe I'm just too impatient.

My book is available in a paperback and a hardcover version, but I'm also offering it as an eBook, more specifically in ePub and Kindle format. A potential reader complained on Twitter, telling me that I should also offer the book in PDF-format. Many people consider me a PDF expert, so why would I not share the book as a PDF?

There are different reasons why I'd rather not respond to that request.

According to a study by Sitecore, 40% of U.S. shoppers would like to reduce the amount of shopping they do on Amazon and 30% feel guilty after they’ve shopped on Amazon.

Last week, the competition regulator in Italy convicted Google to a €102M ($123M) fine because it excluded the JuicePass app from its Android Auto system.

Last week, The Book Shelf fixed the last typos we found in the proof copies of my book Entreprenerd, and we also finalized the eBook version. I decided to do a soft release over the weekend. It usually takes some time for the different sales channels to publish the books, so I used a strict order.

The day before yesterday, I presented the proof copy of the paperback version of Entreprenerd. Today I can present the proof copy of the hardcover version. Although the book looks great, I'll delay the release to fix a minor problem.

I decided not to release my book Entreprenerd before I received proof copies of the hardcover and the paperback version. I'm still waiting for the hardcover, but I received a "Not for Resale" copy of the softcover today.

Something changed, and I don't know exactly what. I know that it was unusual for a newly created website to have about 400 visitors on weekdays. I considered it a success, but I couldn't explain why the website had so many visitors from the start.

On Tuesday April 6 however, the number of visitors dropped with about 300 visitors a day.
