Most of our 5800+ Mashups listed in our directory involve a new site being created from one or more other services, usually web sites themselves. The Kynetx API, which has been called Greasemonkey in the cloud, brings mashups into your browser, right where you're already browsing. The new version of its Chrome extension (coming soon to other browsers) gives users insight into what's creating the mashup they're viewing.
The latest beta release of Chrome includes support for W3C's Credential Management API. The API allows developers to store and sync sign-in information with a browser's credential manager. Chrome support and integration should cut down on the number of sign-ins required by a user while browsing.
