Yes, you're right. They tried to integrate social networks in the browser. But as you say: They went over the top. I'm just suggesting making feeds easier/better and integrating a chat function not dependent on Facebook or any other of the big, closed players.

The other important reason why Flock failed was that they where new. Firefox already has a huge user base who would just get these new functions trough a normal update.

It's about visibility: People can't use what they don't know exists. Most people didn't know Flock existed.
