I'm not sure if I have enough readers to do this sort of thing, but it's worth a try.
Does anyone have any physics questions? Whenever I look at physics blogs, I see lots of commenters with questions in the comments, most of which never get answered. And while there are physics FAQs out there, you usually can't just send in any question and have it be answered.
Since I'm only a physics PhD student, I'm willing to answer questions informally, and even offer my subjective opinion. If I have a short answer, I'll put it in the comments. If I have a longer answer I'll write a post.
I study superconductivity, but I also know a lot about cosmology, quantum theory, and quantum interpretations. And when I read popular articles about physics, I tend to have a better understanding than the typical lay person.
