Would you pay $5/yr for HN?
kirubakaran: I'll give you one data point that you may want to consider:When I was a high school student, it would have been difficult for me to participate in HN. $5/yr was a significant amount of money for me then ($5 = INR240). And I wasn't even poor.Many people I know totally couldn't have afforded $5/yr when they were students. I am sure there are countries where US$5 is even more unthinkable.
