My first blog started as an aid to memory for myself. I did not want to lose all those information that I collected over the course of a project.
I thought that a blog would - in this regard - be helpful in two ways. First, I could go back to recap all this information that I collected. Second, with this content I might help somebody out there having the same issue that I had.
However, there is - at least - a third reason to start writing a blog. John Sonmez from SimpleProgrammer.com created a free email course that explains this other reason in detail. So, if you struggled yourself with starting to write a blog in the past definitely give it a try!
