“Google rolled out enhancements to parts of its Google Docs suite this morning that allow users to make use of third-party “gadgets.” The gadgets, which can be written by anyone with the help of a Google API, make use of data stored in Google Spreadsheets and display it in a variety of different ways (however the developer wants, really). But the gadgets aren’t just limited to making your spreadsheets prettier—they can be embedded onto a personalized iGoogle page, or published anywhere that lets you use HTML and iframes.” (via Ars Technica)
PS. This has great potential. Effectively, it could act as hosted scalable database (resting on google servers) to be used as a backend for strong data-driven apps/websites.
