I recently decided to host my styles.css and various scripts on Google Docs and link them into my website.

I also have all my images hosted through Picasa so that they too will load much faster and consistently across users.

My site has most of its traffic from Japan, Africa, and South America, so I assume there will be a performance boost for my users since my server is hosted in Hong Kong. I (in Canada) have measured my load times to be half of what they used to be. Basically it's a free CDN for my personal stuff.

I'm not too sure about all of this yet, so here's my question: what are the caveats of this setup?

EDIT: So after rummaging through the ToS of both Picasa and Docs, there doesn't seem to be anything wrong with this kind of use.
