Problem/Motivation
Drupal 1.0 was released 15 Jan 2001. 15 Jan 2021 is the 20th anniversary. People want to mark this milestone by looking back on those 20 years. This visualization is one of many celebration efforts.
Proposed resolution
Collect and highlight important milestones. Like the drupal community, this is not all about code, but code is relevant. Please consider events that are about milestones that impacted the direction of Drupal: project decisions, documentation, performance, accessibility, usability, testing, collaboration, educational events, leadership, and community.
Get the word out to acknowledge January 15 2021, Drupal's 20th anniversary. Use the hashtag #CelebrateDrupal
