This is [the original Help Center][1] page, with some minor changes.  It turns out that most of the Off-Topic subjects are already covered here, so I just added a couple of new ones to cover the missing cases:

 - where to find a software library, tool or other resource
 - a product or service recommendation

**UPDATE:** Removed "Freelancing and Business Concerns" from the on-topic list.

> What topics can I ask about here?
> ---------------------------------
> <p>Programmers Stack Exchange is a site for professional programmers

> <h2>What about subjective questions?</h2>
> <p>Subjective questions are allowed, but subjective does not mean
> &ldquo;anything goes&rdquo;. <strong>Please keep it professional at
> all times</strong>. If this is a question you'd be uncomfortable
> discussing with your colleagues in a work environment, it's probably
> not appropriate here, either.</p>
> <p>All subjective questions are expected to be <em>constructive</em>.
> How do we define that?  Constructive subjective questions &hellip;</p>
> <ul> <li>inspire answers that explain “why” and “how”.</li> <li>tend
> to have long, not short, answers.</li> <li>have a constructive, fair,
> and impartial tone.</li> <li>invite sharing experiences over
> opinions.</li> <li>insist that opinion be backed up with facts and
> references.</li> <li>are more than just mindless social fun.</li>
> </ul>
> <p>Questions that do not meet enough of these six guidelines will be
> closed as "Not Constructive". Please see the <a
> href="">Good
> Subjective, Bad Subjective</a> and <a
> href="">Real
> Questions Have Answers</a> blog posts for more details and
> examples.</p>
> <p>Please <a href="/search">look around</a> to see if your question
> has been asked before. It’s also OK to <a
> href="/helpcenter/self-answer">ask and answer your own
> question</a>.</p>
> <p>If your question is not specifically on-topic for Programmers Stack
> Exchange, it may be on topic for <a
> href="">another Stack Exchange site</a>.
> If no site currently exists that will accept your question, you may <a
> href="">commit to</a> or <a
> href="">propose</a>
