It costs 100k to get a tld. So if Amazon takes .author then what about .writer? Or what about biographer, columnist, composer, creator, essayist, ghost, ghostwriter, ink slinger, journalist, originator, playwright, poet, producer, prose writer, reporter, scribbler, scribe, scripter, word slinger, wordsmith, work-for-hire, writer?
Is amazon going to take all of them? So what if they do? Does that suddenly invalidate FirstNameLastname.com/net/me/us/co.uk or FirstNameLastnameAuthor.com/net/us/co.uk?
I'm worried about the opposite trend. That is to say Amazon (or any other company) REQUIRING people to buy a certain tld before allowing them to use certain services (want to sell in the apple store you must buy a .apple tld, want to publish a book you must buy a .book tld)
