if the 'Replies' are more than 10% of the 'Views' then there's a good chance that the topic has wide appeal and has attracted replies not only from a good many people, but also a diversity of posters (not just one or two going back and forth - though this does happen). As a bit of a generalist, I find that these posts are the ones that I tend to be most interested in and contribute to.

if a sizable proportion of regulars were to use this as a guideline it could seriously skew the outcome.
