They seems obvious to you now but they weren't at that time. Not that I am a Zuck fan at all but he deserve credit for that and that probably demonstrate some creativity and vision from him. No ?
MySpace existed. Facebook didn’t really add much beyond that to think that others wouldn’t have come up with the same idea in Zuck’s absence. In fact, the lawsuits from the Winklevos twins would seem to imply just that.
I think the main value add - looking back on how I perceived FB when it came out and why a lot
of us started using it - was branding and a cleaner, fresh design. And the newsfeed was a new concept...
