Everything that's wrong with LinkedIn, is done right on Polywork. I have a huge following on LinkedIn but I can NOT wait until we all move over. The network is welcoming, the features match people's professional lives much better, and it simply is an all-round improvement from design to functionality.
I started using Polywork recently and was pleasantly surprised by the deep well of opportunities listed here. It was nice to see a site for someone like me -- I dont just have a job, i'm also on boards, i'm an investor, I want to participate in community projects. Polywork was great at helping surface interesting opportunities for active people looking to get involved and grow themselves across many dimensions.
