You've installed Drupal. Congratulations! You can now create pages and stories that contain text. Sorry, no images. Or video. And if you want the text to be formatted with bold, colors, bulleted lists, or links, you'll need to do that manually, using html tags. At this point, you might be thinking, why all the buzz around Drupal? Is it useful for anything besides creating a simple blog? And if that's all you want to do, scrap Drupal, and get an account on WordPress instead. But then, hopefully, someone fills you in on the secret to Drupal. Despite initial appearances, it's actually super powerful! Anything you can imagine, you can do! There's over 4,000 modules on drupal.org to choose from. All you need to do is figure out which 100 or so you need, and voila, pure website awesomeness!
Drupal's basic node structure works well for presenting articles, but sometimes clients want to embed images, video, or other block-like items in the middle of the text, such as top rated comments or a snippet of interesting text from that article.
