- I don´t want to overload google with the “api 653 question” keyword
- I need to study for my API 580 certification examination on December, 19th.
- I need to make my posts more appealing to comments, questions and answers.
Those are enough reasons to make this break.

That´s why (besides some writer´s block) I want to try this subject this time.
