Jetpack is the one plugin I cannot run a blog without. From Related Posts, share buttons, Publicize, Comments and the subscription system, to site stats and site monitor, you will love Jetpack too. They also have awesome happiness engineers who will help you with all your issues. Jetpack rocks.
I am amazed at the functionality offered by Jetpack. It's one of the main reasons I use WordPress versus other web site development tools. Jetpack offers a range of things that make it much easier to manage my multiple self-hosted WordPress sites from one location. I'm also learning about and using new features of Jetpack all the time. It has really helped me get my sites online, keep them running, and make them more appealing to my viewers.
Jetpack is lightweight and has quite a few awesome features. It's also supported & backed by the makers of WordPress.com, so you can trust it. Jetpack is one of a select few plugins that I install on every site I build. There are few must-haves in this world, but this plugin is one of them.
