The [qiskit] tag has over 1200 questions on QC.SE. There are lots of examples of "good" questions and helpful answers. However, in my limited experience, a number of qiskit tagged questions are closed due to the fact that they are strictly programming questions about the qiskit SDK rather than questions about quantum computing, which is totally justified in my opinion.
However, I just discovered that Qiskit actually funnels users to QC.SE (see the bottom of the landing page here under the support heading). Not only do they link to QC.SE, but as far as I am aware there are not any IBM-supported forum pages for Qiskit, other than documentation. Now perhaps that is just because Qiskit is an open-source project and isn't as intimately linked with IBM products as of yet.
Anyways more to the point, as commercial quantum computing continues to ramp up and we see more and more quantum computing SDKs become available, I think that it would be prudent for QC.SE to have a policy on offering support for these projects (or do we already have a community agreed-upon stance here?). In particular, if qiskit users are being linked here from the qiskit site and then we are closing a lot of qiskit programming questions, I can understand some confusion from users, but perhaps this isn't our problem?
I just took a look at the related post Would it make sense for there to be a separate SE site for "quantum programming" or "quantum information software", versus quantum information theory? where the more basic quantum software vs. the theory of quantum computing was brought up. I guess many of the same discussion points exist there, but I wanted to highlight the specific issue of Qiskit linking their support directly to this site.
