I thought it will be BLIND but for founders/creators. It is just polished/hyped up Linkedin. Did beta/testflight but deleted when it got noisy. Currently using Read.cv which is better looking and where people don't brag; ititss like early Instagram; until some asscorp will destroy it.
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.
