Drupal has a good name as CMS(Content Management System). I didnt’ know much about what it is or what it can do. But after experimenting with setting two Drupal-powered site within a day, I think I have grasped the essence of it now.
And I think this can become a great thing for my site!
A little sad I had to abandon WordPress for the weblog, but it’s much better now integrated with the rest of the site.
