Webhooks are a simple paradigm for developing instant notifications and mashups based on simple HTTP requests. With HookPress you can set up webhooks so that a specified URL (a public service or something you set up) is requested when certain WordPress actions occur. Possible uses include generating push notifications or using non-PHP web technology to extend WordPress.

To learn about the various hooks WordPress provides, please consult the WordPress Plugin API's Action Reference and Filter Reference. Not all hooks are supported yet, but more are in the works.

To learn more about webhooks, take a look at the webhooks blog as well as The Pushbutton Web by Anil Dash. Webhooks champion Jeff Lindsay's excellent slides are a particularly good place to start.

To write and host a target script you can of course use your own server but you might also consider Scriptlets. A dead-simple tool which logs any requests thrown at it, test.php, is included with HookPress as a great way to test requests generated by your webhooks.
