Google AJAX Libraries API

This is pretty cool. We’re currently internationalising a couple of our social networking sites for the US and other international markets and I can see real benefits in using this approach, not least of which would be:

• Caching can be done by Google… we don’t have to write and maintain additional code in our apps for this
• Files are Gzipped
• The files are hosted by Google which has a distributed CDN at various points around the world, so the files are “close” to the user (UK visitors get a copy from a UK based CDN, US Visitors from a US CDN, etc)
• Because the libraries are hosted on the same URLs, if the user has used another application that uses this infrastructure, the file may already be cached on their local machine.
• Google servers are able to deliver content fast!
