A lot of people who run Wordpress have clients who need a nice, easy user interface to be able to update their site. Do you have any suggestions for software that fulfills that need and is "secure, not bloated and easier to develop with".
This is clearly opinion, and should be taken as such, but I absolutely loathe Wordpress' admin interface. I'm sure at some point it was a nice, easy user interface but those days have passed. Anytime I have the misfortune of being thrown into a Wordpress backend I have no idea how to get anything done.
After the second Drupal flaw in two weeks that enabled anybody to log on my server, I've decided to remove anything wrote in PHP from it. I'm not here to babysit software.
As a bonus, if you want anything too fancy in Mezzanine, you can just escape away to Django. Beats being thrown away in PHP by miles.
