As a 'regular' on another stack exchange site that's recently started looking at this one, I do think this site might have some problems around questions like this.
Generally speaking, stack exchange sites are question and answer sites rather than forums for discussion and debate, and good Q&A sites need objective questions and objective answers. As such, its hard to criticise people for following those guidelines when maintaining the site.
There are a large number of questions here that essentially can be answered with "That's up to your [current/prospective] boss" or "you need legal advice, which we can't give". This is what drives a lot of questions to be closed, I think, as most questions around employment will shade into at least one of those areas.
What's left is the well qualified opinion. Essentially a professional opinion rather than the rambling thoughts of a random passer-by. This is true even on the IT based sites where you might expect us to deal with facts. A coder's solution to a problem on stack overflow is a professional opinion expressed via code, and that's acceptable. So it is here, if you ask me.
But yes, it's a difficult line to walk, especially on sites that deal with "soft" issues like this one.
