Dusen now takes question content into consideration as well.
Enabled user profile pages (https://trello.com/c/fnQlNjUN/95-user-profiles-be-able-to-see-other-people-s-profiles-with-basic-information-and-karma). Refactored some hajdar's code for user badges into its own Kudo service so it is reusable throughout the app. User profiles now display most recent q's and a's by user. Some model bugfixes.
