This is a good question. First, I think that LinkedIn includes too many features. Influencers, groups, pulse and stuff like that. I'm still trying to find a use for groups. Something more focused on networking would be great. Second, as I mentioned in a previous message, LinkedIn caters to recruiters because that's how they get their money, and to me it makes it insufferable. There is this running joke "Being a developer on LinkedIn is like being a woman on match.com". I believe it would be really hard to monetize a sane and clean website for professionals without turning into this spamming juggernaut.
