Advogato is an online community site dedicated to free software development, created by Raph Levien. It describes itself as "the free software developer's advocate." Advogato was an early pioneer of "online diaries", which later became known as blogs, and one of the earliest social networking websites. Advogato combined the most recent entries from each user's diary together into a single continuous feed called the recentlog. This directly inspired the creation of the Planet aggregator somewhat later.
