FriendFeed

FriendFeed was a social media aggregator platform that centralized updates from various online services like Facebook, Twitter, RSS feeds, and more into a single feed. It allowed users to follow multiple sources, comment on updates, and share content in one place, streamlining social interactions and content discovery. Launched in 2007, it aimed to make social media management easier by aggregating activity across different platforms. Facebook acquired FriendFeed in 2009, but it was eventually shut down in 2013, with its features integrated into Facebook's ecosystem.
