Lets be honest, the variety, quality and low cost of Joomla templates far outshines most other CMSs. More than anything else, its the reason I hear from people when they decide on Joomla.

No surprise then that Joomla's templates are being imitated:

WordPress: RevolutionTheme.com. $59.99 for the template.

Drupal: Roopletheme.com. Apparently they initially intended to sell these templates but have since decided to offer them for free. Take a close look and you'll notice:

• The very Joomlaish block positions, User1, User 2, User 3 etc.
  


• The demo is directly modeled after Joomla template clubs.


• Their templates actually make it easy to use dropdown menus in Drupal. That has long been major Drupal design weakness.


• The similarity of LiteJazz to Rockettheme.com's Colormatic template.
