As of march Reddit does track all outbound links on their site. This allows Reddit to build a database that links users to the external links they visit from the site, although they claim that their sec. policy would make it impossible for them to do so.
*Do not forget to deactivate this feature, which is turned on by default: Preferences->Options->Privacy Options-> Uncheck allow reddit to log my outbound clicks for personalization
