At Jon's request, I am expanding a comment into an answer.
Jon, I'm sorry -- I wish I could give a different answer. But I can't.
I do not recommend this site for Jews now because of the religious nature of the site. The presence of my answers there is problematic enough that I made a plea for their removal; I believe the community team gave my request thoughtful consideration, but that request was denied.
If you are considering participating there, particularly to contribute answers that teach torah, I strongly recommend that you seek rabbinic guidance first. I have now done so (belatedly) and no longer participate there. If you do participate, I recommend a short disclaimer on your answers (here's mine, at the bottom); this practice is permitted by SE (so long as you don't use it as a soapbox, of course).
I became active on Biblical Hermeneutics early on (in 2011) and was for a time the #2 user by reputation. There are a lot of questions that don't apply to us since they consider Christian books too, but it seemed like I could provide useful Jewish answers to Tanakh questions, and since the site claimed not to have a doctrinal basis (as noted in this question, and also in the site's "about" page and numerous places on meta), that seemed like an ok thing to do. I received positive feedback from users who only ever learned the Christian spins on our texts and aren't able to read the original Hebrew, so I thought I was doing a good thing by countering some mistaken notions that Christians sometimes spread. And there are some smart, educated people on BH who I enjoy(ed) interacting with.
However, I no longer recommend this site for Jews. Why? Because that doctrinal/dogmatic neutrality hasn't worked out in practice. Despite the charter, and despite a massively up-voted meta post saying "Any discussion of beliefs, doctrines or theology belongs on Christianity.SE", too many answers (and sometimes questions) assert Christian truth claims that are decidedly counter to the Tanakh (now with explicit permission to do so). Efforts to move them toward neutral or descriptive statements failed (that's +14/-7 at this writing, for those who can't see, which wasn't enough to effect a change). To me, the environment on the site is not only not welcoming but rather hostile. This was not always true -- I would not have participated initially had it been -- but it is true now. I think it is a hostility of negligence, not a willful hostility, but they also have not moved to address the problem:
Since most people here (and all moderators) agree with those basic assertions of truth (if not all the details), they don't see the problem even when someone objects. To them it's like saying that the sun rises in the morning. To people in this group, doctrinal assertions in posts add character and couldn't possibly do any harm. [...]
I came to teach and learn in a classroom. But people brought in an altar, crucifix, and communion wafers, and the custodians gave them directions. (September 2013, source)
I had a realization on Rosh Hashana during the shofar service when I read the "arise, you slumberers" Rambam passage including "you are wasting your years in vain pursuits that neither profit nor save". That seems to apply to my Jewish voice on BH. It doesn't seem to be profiting or saving anybody, and after further consideration I realized I'm actually doing harm. I certainly can't in good faith contribute any more answers, and continuing to expose myself to all the Christian evangelism there is a bad idea.
Sites change, and perhaps some day Biblical Hermeneutics will move toward the more religiously-neutral, scholarly state it once aspired to. If the site changes, you should of course take that into account when you seek your rabbi's guidance.
