@molecule obvious to you and I. I wrote this to inform those who think it is a good idea to use S3 as a CDN, that it isn't. If we can educate a few developers then we (this awesome community of hackers) are making the web faster.

You're not making the web faster, you're shilling for your employer by comparing their apples to a competitor's oranges and proclaiming "our competitor's oranges make bad apple sauce!"

Failure to mention CloudFront is disingenuous.

So why is the title of your post "CDN vs S3"? Shouldn't it be something like "Don't use S3 as a CDN"?

To be honest, your post feels like spam for MaxCDN.

Honest question: Do you actually know anyone that thinks S3 is appropriate as a CDN?

Tumblr and Twitter both used to, and I've met a bunch of developers at meetups who rather than think S3 is a CDN, do not understand what a CDN is.

Using S3 for file hosting is still a better solution than using a raw box (or shared virtual hosting) which is what most people who use S3 instead of a CDN would have been doing otherwise.
