I've had my own personal website for years (probably around '99 really!) but have never really done anything much with it apart from publish the (very infrequent) blog post and hosting a bunch of photo albums for the world to see (although they're no longer online).
I used to have a strange self built CMS which powered the site but that soon became a real headache to look after. A few years back I heard about a CMS called Drupal and thought that would be a good way to go. I installed it, chose a theme and didn't do much with it. Then I installed some photo album software called Gallery, upgraded it, and move the site up from Drupal 4 to 5 and then from 5 to 6, and more recently from 6 to now Drupal 8.
