On Hive Index, the default Popular sort surfaces Information Architecture Community first. Popularity reflects visitor interest in communities on the site, not a universal quality score. Use the sort menu for Ratings, Largest, or Newest.
Listings are submitted by community builders and researchers, reviewed for topic relevance, and updated with platform, feature, member, review, and traffic data where available. Member counts are approximate. Popular reflects visitor interest in communities on the site, with richer profiles breaking ties. Ratings, Largest, and Newest use review scores, reported member counts, and listing age instead.
This page was last updated 5/8/2026, based on the most recent change to the topic or its listings. We refresh entries when communities are submitted, claimed, or reviewed, and we update member counts, features, and traffic data on an ongoing basis.
