Although I am not able to compete even for 10th position. I will not call it "rat race". If some blogger are able to write more, I admire them. when we are calculating prize for per post for top bloggers, we must consider how often they get opportunity to get 20K. let’s just accept this contest is also has prize for people who can produce more. Quality is not ignored as big prizes are reserved for them.
Is it not a good formula where quality is given biggest prize, quantity is given bigger prize and just submitting valid post is given sure prize?
I think top 20-30 people will create so many posts that this will eventually help marathon and whole blogger community for new contest.
PS:
One more suggestion as this contest is going to run for 30days, moderation after each week/10days will help bloggers to get actual count.
