I liked the feed feature; I understand it wasn't used a ton, but I did enjoy looking around and seeing what people were making. It's now just another portfolio site in the vein of caard. I already have a personal site, so there's not much need for me to visit since I can't really find anyone else.
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.
