Automattic’s Jetpack plugin has come a long way! It’s been much-maligned in the past for being bloated and slow and for that reason many developers wouldn’t touch it with a 10-foot keyboard.

From the code side of things, developers will be pleasantly surprised to discover that it has been sprinkled with lots of actions and filters. So, while Jetpack is still generally marketed to entry-level end users, there are actually some nice Easter eggs for developers who want to customize things a little bit for their clients.
This article provides some code snippets and examples of a few ways to customize Jetpack modules.
