Many of today's web sites and other online applications aren't just about presenting a few facts, but are about providing content, from blog posts, comments, Tweet feeds, and short headlines to product information, audio, pictures, videos, PDFs, and more. This is increasingly true not just for media companies but also for a growing number of businesses, not to mention government entities (agencies, departments, cities, states, countries), transportation/travel, organizations, and more, along with SOHOs and professionals, families and even individuals.

Much of this content is meant to be put in by non-HTML-experts, who in turn aren't the site developers or administrators. And many designers and developers want higher-level tools than the HTML editors of yore to create and manage these content-intensive sites.

"Managing content means managing user accounts, managing the media, and managing the content itself, the article copy, the menus, overall design," says Mitch Pirtle, co-founder of Joomla!, one of the two best-known and popular web CMSs. (The other is Drupal; both Joomla! and Drupal are open source projects.) According to Pirtle, Joomla! users range from a world-wide company with 20,000+ staff to "a site for his two kids." Other Joomla! users include MTV Networks Quizilla, the IHOP restaurant chain, and Citibank (internally).

Here are some tips, advice, and best practices from several Joomla! developers, including Mitch Pirtle.
