I'm using it since beta and Polywork is just getting better and better. They clearly know what they're doing and how to be a solution for everyone in terms of collaborating and freeing someone from a job title itself.
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.
