Google has added a new feature to Drive: You can now serve up web content from within your Google Drive folder, even ones that run JavaScript. All you need to do is upload your HTML files and assets (e.g., images) and make them public

The Google Developers site has more details on publishing a folder as a website, but essentially, besides having the folder and site assets public, you also need to link to the files in the folder using a "webViewLink" code. If you don't have an index.html file in the folder, Drive will display a list of the folder's contents

This could come in really handy if you don't want to spring for your own web hosting. You could do things like publish a photo gallery, an online resume, or a personal start page. There's no word on bandwidth or other limitations yet, but you can keep an eye on the discussions on Stack Overflow if you have any questions
