The final thing I want to describe in this chapter is the feature of importing and exporting your content. By default, WordPress allows you to "take" content from other places and publish it on your site. There's a number of platforms supported, including former Blogger, LiveJournal, Tumblr blogs, and more. You can see the complete list by navigating to Tools | Import (it's also the starting point when importing content), as shown in the following screenshot:
If you want to import content from any source, after you click on any of the links visible on the preceding screenshot, WordPress will prompt you to install some plugins to fully enable the feature. Plugins are the topic of the next chapter, but the way WordPress uses them for importing is really a hands-off approach so you don't have to know much about plugins themselves in order to be able to import content.
Now, importing content from each of the available platforms is a bit different...
