I submitted this link: http://martinfowler.com/articles/serverless.html#drawbacks with the title "Serverless Drawbacks", as that was the recently added section. Guess someone changed it, but it's not a dupe :)

In any case, it seems that "Benefits" has also been added since the last HN discussion (revision history: http://martinfowler.com/articles/serverless.html#Significant...).
