Since its public launch in 2006, we have enhanced WordPress.com with a number of add-on services to make blogging better, safer, and more fun. Many of these services are also available to self-hosted WordPress users via a series of WordPress plugins:
Jetpack — Jetpack provides security, performance, and growth tools for WordPress sites. It gives you everything you need to make your site safer and faster, and bring you more traffic. Besides a comprehensive suite of tools, Jetpack also offers individual plugins that allow you to install only the features you’d like.
Crowdsignal — Polls, ratings, and surveys are a great way to engage the visitors on your site. Our Crowdsignal plugin makes it easy to create polls right from your WordPress dashboard and integrate them into your site. Crowdsignal offers unlimited, free polls and ratings, and free and paid options for surveys.
