I'm a lurker on Skeptics.SE, and several other SE sites. I personally don't really have the expertise or time to answer questions there, but find the content interesting. So I subscribe to the weekly newsletter.
However, often when I get the Skeptics.SE newsletter, and also sometimes the Home Improvement newsletter, I open one of the top questions, only to find out there is no answer. For example, here are a few from the Skeptics.SE newsletter that I just received:
- Did a group of U.S. women propose to send black kids instead of dogs to space?
- Does storing powdered coffee in the fridge preserve its flavor better?
- Is 90% of the large fish biomass gone, when compared to pre-industrial levels?
Those are also the first three things in the Newsletter. These are in the "top questions" section, not the "can you answer these?" section.
I suggest that "top questions" should be limited only to questions with answers. Ones which don't have answers should go in the "can you answer these?" section instead.
