I felt that this is more in general trend with most websites, especially with visits from India. Despite being one of the most populous country with "high internet penetration", Indians usually don't seem to visit websites.
I know the post's is the data is from HackerNews visitors over a certain period of time -- when it was working time across USA's timezone.
Even on my own personal website (I'm Indian), India is like the 4th highest visitor with a hugh margin of difference from USA's visit. It, however, does catches up with USA to my family website though the difference still remains high with the top visitors - USA.
