This is the debut of a new weekly feature on ScienceBlogs. It's called Ask A ScienceBlogger, and it is Sb's own mini blog carnival -- a chance for the bloggers to weigh in, briefly, about a question of general interest.
This week's question is:
If you could cause one invention from the last hundred years never to have been made at all, which would it be, and why?
To suggest a question for the next Ask A ScienceBlogger, leave a comment, below. (And stay tuned for a dedicated email address, soon.)
