There is a new website (newish–It says it launched in 2010, but it’s not clear exactly when…) called Jewish Values Online, subtitled multi Jewish perspectives on morals and ethics. At JVO, you can do a search for an answer to your question or ask new questions.
Let’s set aside their missing hyphen and the fact that their list of categories goes far beyond morals and ethics. Let’s check out their panel of 71 experts:
First of all, they’re all rabbis. There are no Jewish scholars of any other sort of training, no cantors nor any academics.
Second–and more egregiously–the rabbis are listed as being in one of three categories: Conservative, Orthodox and Reform. There are no Reconstructionist, Renewal or unaffiliated rabbis on the panel of experts.
Aside from the exclusion of Jewish voices that don’t fit into the trichotomy, it may also make some people cling to one panelist’s answer, ignoring other answers because they’re from another denomination.
I took a look at a few questions on the site and found that, in many cases, I would have been unable to determine which rabbis were from which denomination based on the answers they gave.
