Almost forgot to mention the most important aspect, the site is invite-only. It's read-only to the public.
I'm not sure any of this is BAD, and I may just be stupid, but the 'why the hell should I care' bit seems to be confusing? Is it a job board, or a news/content sharing site? Both?
The next step I planned to take was to expose the Posts tab on the landing page.
Down the road I expect to make the landing page the popular posts page and the Request Invite links would take you to what is now the landing page (the request an invite page).
That's the 3-step process for exposing the posts more and more as I currently have it planned.
