Post Status probably has some of the best WP business-specific content in the community, and I say this as someone from a competing publication. I’m not overly active there, but I enjoy the atmosphere and some of the discussions. I am also interested in seeing where things go now that Cory Miller is on board.
I have heard from others that the job section has been beneficial for them, but that’s not something I’ve used at personally.
More than anything, I think we, as a community, need to continue supporting as many WordPress publications as possible. That means throwing some dollars to places like WP Mainline, Post Status, and elsewhere. They raise the awareness of the WordPress project and provide avenues for discussion outside official channels, which is good for the entire ecosystem. Definitely support the places you find value in.
