My problem with Kaggle is that they are more greedy then Apple, Kickstarter and Paypal together. Apple takes 30%, Kickstarter takes 10%, Paypal takes 3%, but Kaggle takes 50%!
I once asked them what the price would be to start a competition to outsource a difficult machine learning problem. Their answer was: We would need to pay $20k, if we want the winner to earn $10k.
Thats when I stopped thinking about those greedy bastards.
