The current slogan is community plumbing.
Here are some proposals for a new slogan:
Come for the software, stay for the community
has been proposed as Drupal's new slogan, an alternative to the unclear "community plumbing". The thread was started by chx at Change community plumbing.
"Come for the software, stay for the community" is much more reflective of Drupal and a clearer message for people
"Come for the software" clearly states that we think the software is worth coming for, heck it even says its software.
"Stay for the community." is warm and inviting, it clearly sets a tone for the user and reflects the real reason Drupal is great.
Dries: "While I like this slogan (I think I might have set of all the tweeting), it seems too inward facing, so to speak. It probably resonates with the 10,000 contributors or so, but not with the 500,000 users. Reality is that the vast majority does not stay for the community. Sounds like a great slogan for groups.drupal.org, but I'm not convinced yet it is the proper slogan for drupal.org. I need to think about it some more."
