Flock, social browsing
Before RockMelt was born, Flock took the social networking world by storm. Based on Firefox architecture, the social browser has built-in social sharing and bookmarking as well as an easy built-in blogging tool that allowed users to save time in their content sharing.
In January, Zynga acquired all of the Flock talent but the CEO and the software remained, according to TechCrunch.com. Over the years, Flock has seen $28.3 million in funding.
This week, Cisco also announced the end of the Flip camera lines and Jott voice-to-text closed their doors. These three companies all have various reasons for closing down ranging from failure to radical success leading to acquisition, but the startup graveyard is just starting to see its first rash of residents for 2011.
