Hello jakeheller . 

               I agree that email notification for new comments is probably the best way to go.  I only joined about a week ago, and was keeping an eye on my one and only contribution.  After a few days, I wasn’t getting many hits so I linked from Renderosity.  It took a few days to take effect, but when it did, I got nearly 500 hits in the first 24 hours.  One of those hits was a comment.  The comment was really a question.  If I weren’t monitoring my stats daily, the customer would have thought I was ignoring him/her because he/she was not important.  By responding quickly, he/she has a better opinion of sharecg, and is more likely to return and browse the content.  With automatically email, it gives us a chance to answer all of their questions, without missing one or responding to the same one twice.                                           -David
