Am I the only one that found this article poorly researched and misleading? It mentioned that using "cloud servers" lets you quickly fix bugs, rather than having to "rebuild" your code before you fix the bugs. How does that have anything to do with cloud services? Secondly, I'd like to know how many of the apps that Heroku hosts are actually production apps. I know I host at least 15 apps on Heroku, but all of them don't have any paid addons, they have one dyno, and none of them are actually the production server for the application.
