I was teaching a design class at a local community college (pre-google drive) and my power point presentations weren't syncing with their system, so a class or two I was stuck with nothing visual. Imagine a design class with nothing visual - yeah.
So I decided to start one of these new fangled "blogs" so that all my information was in one spot that could be accessed online. It worked!
5 or 6 years later -- that class is a thing of the past, but the blog has definitely picked up and morphed and changed.
To add to that -- a couple of years ago -- I decided to turn my blog into a resource for readers and other bloggers and split it into 4 categories: Food, Photography, DIY Design and Modern Garden Living. Those categories stuck and I do very little beyond them. :)
