There's also the web usage/development issue.The percentage of developed sites in the new gTLDs is often much lower than that in the legacy gTLDs and the ccTLDs.Not al new tlds are loosers. Hold backs, outlandish prices for registration and renewals are holding acceptance back.
That's the business. If the same regulations were applied to .COM/NET then both gTLDs would lose a lot of registrations.Why not pay 1 million for a single word .com as opposed to $50K every year for a single word.whatever? ICANN and registrars have rigged the market and are reaping the rewards.
