I've been workingwith CMS for several years. One thing that has been consistent has been the theme situation.
Themes have always been a pain and since I'm not a graphics whatzit kinda guy....creating anything truly creative is out of the question.
I tried my hand at themes and moved onto other things. LOL
I can pump out the sites, but I'm always restricted by themes. Restricted, may not be the best choice of words. I should say my choices are pretty well bound by the theme I use for content display.
Recently, I started using Drupal and the Garland Theme. I really like the ability to change the colors so easily. I sure would like to see some additional themes that make use of the color wheel. I prefer color changes in my sites, because they load faster and work well pretty well on any browser or connection speed.
I realize from reading the forums that Drupal has been negatively looked upon for the over simplfied types of themes available. I prefer flexibilty and speed for accessing content on my sites, which Drupal provides. I won't name names, but there are some newer theme additions to Drupal that look a lot more professional.
I look forward to great new themes, but I'd like to encourage theme builders to keep in mind that using color and fewer gifs/png/jpg mean faster sites.
