Is there a good alternative to Drupal? I haven't peeked under the hood but as a user I was super impressed with how easily I could snap together a heavily customized Drupal site with user-driven contributions that were well-structured. Not just blogs, but we were running maps for the Cube /Sauerbraten game engines with screenshots and compatibility-tags whatnot, and use flexinode to provide a consistent structure to the list of content. Users could rate the content, comment, moderate comments, etc. The plugin system was well-curated and the config pages were powerful and clear. Drupal may be awful under the hood, but I was very impressed with how much I could do without peeking under there or even googling "how do I X?". I'd love to see somebody take a modern tech stack like .Net Core and Postgres or something like that and build a cleaner version of same.
