In my own way, blogging as a developer is a way of expressing myself on the web whether it be because of finding something interesting, solving a problem or in general just having that space to write my thoughts down. It's also pretty useful for when inevitably I forget bits I do on a reg like setting up services and new project packages to install. It gives me space to free my mind and be creative, accountability in a way and may be even by helping a reader with a problem I solved - even better.
