Development of Core Features
Several key features that define modern Reddit were introduced during this period:
Self Posts: In 2009, Reddit introduced self posts (text posts), allowing users to create discussions without linking to external content.
Reddit Gold: Launched in 2010, Reddit gold (later renamed Reddit Premium) became the platform's premium membership program, offering additional features and helping to support the site's operations.
Mobile Interface: The first official mobile interface was introduced, though third-party apps remained popular.
Subreddit Growth: The number of subreddits exploded, with communities forming around increasingly specific interests and topics.
