I have found one full time job, a few clients, and have seen/connected with a few groups I know from places outside hacker news here.
Personally, love reading the boards to find new companies and technologies that I didn’t know about and leads me down the rabbit hole.
I would think that there could be some benefit to having more non-technical job posts on the board. As to a stand alone who’s hiring... I would think it would be harder to get people to post to another thread as opposed to getting more non-technical roles and filtering.
