I've used a great deal of free and premium themes from
http://themeforest.net and
http://www.templatemonster.com oriented to both Wordpress and Joomla I have no real complaints about Joomla CMS after using is for about two years, but I'd like to say that there a strong reason for all the fuss over Wordpress. Both WordPress and Joomla can be utilized to make amazingly creative websites, both can be installed easily on your own server, but my personal preference still goes with WP. I think it is just a little more user-friendly platform carrying a larger selection of plugins than any of the competition. By the way, does anyone know the differences between Wordpress and Joomla, from Google and SEO standpoint?
