I happened to look at the front page and saw an interesting (to me) question which was appropriately closed as seeking personal medical advice. I edited the post to remove that aspect.
I haven't been following the shift in the site or the progress towards that change, so I don't know if this is now on topic or not. Clearly it's a layman's question. It's not very complicated, but it's very common. It tends to be brushed off by doctors with a brusque, "Stop biting them," or advising the patient to apply bitter polish to the nails. A nice, from-the-literature answer might be helpful.
On the other hand, if this were actually a physician to physician site, would asking what has been successful in nail-biting patients be any different?
I did read the scope Q and As, but don't know how or if they are being implemented.
What does the community think? Does it fit with what the goals of the site are now?
