I have tried every blog/cms system listed on hotscripts.com and opensourcecms.com (few hundreds), always with newbie-user-on-my-mind, and have to say, I (almost) prefer WP, especially after introducing pages, not only articles/categories, but there are still two issues which effectively stops me in going with WP:
1. templates are still messed with php code (security! in multiuser environment)
2. granular privileges and users levels are still cryptic (numbers)
all above (2) issues/features are really well implemented/resolved in many less mature than WP systems, to name few: lucidcms.net , cmsmadesimple.org or (I'm sorry ;) textpattern.com
there are many posts on this forum on this subject (or near it) but these issues are still untouched
can you say something yes/no about plans on changing it to more mature level ?
