Good question. I’ve only skimmed over CiviCRM, and yes, Drupal/Wordpress/PHP certainly does not endear it to this particular nerd, but that of course doesn’t mean it doesn’t deserve more of a look at.
In my travels I haven’t come across anyone who uses it, does that mean it fell down, or have I missed a great modern success? If it isn’t any good, will my approach going to make the same mistakes? Maybe!
Another immediate, not necessarily accurate, opinion is that, based on the UI, it feels like it aims to meet “business needs” over user needs, pushing it into the professionalising thing I mentioned.
But I don’t know! If you have any knowledge/thoughts I’d greatly appreciate it.
