I'd imagine so, there is a comment system for a reason. Although, most tend to stray away from long articles such as this one. Hacker News would benefit from a summation web application for articles like these.

Taking away someone's opportunity to be employed elsewhere oversteps the line between the employer and the employee's personal life.
