I think the author is making it a bigger deal than it really is, nothing stops google from bringing down the google plus or any other service he might be using(just like google reader or wave) so according to his logic (printed on business card etc...) you can't even have a long unfriendly URL because google can shut down google plus any day they want to or just start charging people.
