Hello,
First some background: I discovered Drupal in 2006, made several failed attempts at migrating to it (partly because of Drupal, partly because of other unrelated reasons) and I'm now trying to convert from Dotclear to Wordpress to Drupal one more time (Dotclear to Worpress is because there is not Dotclear to Drupal migrating tool). I am not a coder, I am more of a usability so-called expert.
Below you will find my vision of how to improve Drupal.
First: let us call a spade a spade, especially when it may fuel motivation by giving a foreseeable goal. Drupal main competitor visibility-wise are Joomla and Wordpress. Competition is direct with Joomla, indirect but rising with Wordpress. Drupal uses a top-down approach, from CMS to “mere” blog, whilst Wordpress uses a bottom-up approach, from blog to full-fledged CMS. Drupal competes with Wordpress.
Wordpress competes with Drupal.
Second: the first impression matters a lot. What is the first impression? Installation.
Now, with the objective of making it better, I'll survey my own installation of Drupal. From scratch. And I'll be blunt (well, somewhat).
