Hi, I am author of this blog post. If you have any questions, feel free to ask.

Main idea behind blog post is to explain what kind of questions you can ask when dealing with graphs to uncover hidden knowledge. Problem is often that although it seems at first easier to work with Relational databases due to the way people are used to think about databases and finding something in them, it turns out to be slow and nonperforming solution. And when you realize graph databases are more suitable when dealing with finding patterns due to lot's of node hopping and explorations, people don't know how to model such question or don't know what you can ask graph database. This blog post intends to help you with first steps and get some ideas.

Let me know what do you think.
