Wordpress is good. No doubt about that. But once you have more than 70-80 posts, the link to previous (old) posts either disappears or is not clickable even from the admin panel! I am using Drupal. It is gr8 CMS. Blogs, Forums, Polls, Themes, Posting anyone of them using Blog API and many more! It is very cool. If the Blog Plugin is enabled, then your users can maintain their blogs on your site itself!
