Just wanted to try to keep track of some interesting modules mentioned at DrupalCon:
Organic Groups – create groups that users can join. groups can have own home page and context
PURL – use for embedding context info into URL. Use this instead of setting session variables
Context Spaces – more granular variable level overrides than using Context or Panels or Blocks
Managing News – RSS/Atom aggregator with visualizations
MapBox – Custom maps
Features – exportable configurations management
Strongarm – override database variables
Drush – commandline tool for Drupal admin. Use with shell scripts or drive it through other tools
Deploy – migrating content to/from different environments
Calais – Thompson Reuters Calais auto-tagging for content
Display Suite – block-like visual display tools for nodes, views, comments, users, and more
Other tools:
Puppet – Ruby based tool for server configuration management
Splunk – log file consolidation
Phing – ant-like build tool with pre-defined PHP-ish tasks already defined (like phplint for syntax checking)
TypeKit – font resources
