You have much more work to do. I'm using FF 3.5.5, Windows (at work presently).
The theme is plain, and I have no problem with minimalistic - but this is good old fashioned boring. Maybe add in a gray border color or a subtle background color in the dialog boxes. Meanwhile at the bottom it's as if your footer came from a totally different web site theme and you glued them together.
Consistency in design elements, i.e. header/footer/content and so on is more pleasing to the eye and easier for users to navigate. Also, the focus becomes content and not a "heavy" (dark) footer which overpowers things.
Work on proper alignment and spacing of photos and text - add a little space around the photos, make sure fonts are not cut off or collide with other elements and wrap properly. The photos to the left of each blog entry should align in the same position for each.
What *is* Digital Mac Living? Use a little header area to explain the focus of the site, its intended purpose - explained in brief beyond the title alone.
Avoid blocks of large white space between other content (right side, 50% down) - i.e. think of your site as a city, with streets (borders, dialog boxes, horizontal rules, etc.) and buildings (content) --- you've got "unused commercially zoned space" which is doing nothing productive, removing focus from other neighborhoods if you follow the analogy.
The header can be so much more, without really doing much - maybe as simple as a nice background image, a fancier logo.... anything other than plain text on white. Minimalize the footer as noted earlier, but not necessarily the header into nothingness which it is now. BORING.
I'm also not a fan of the font you used for the digital look, although I understand why. But if you're gonna use it - be consistent and use it in all content area headers. Otherwise it looks like a gimmick.
Example of minimalist theme with proper alignment and color palette that you might consider:

Remember, this is not to say I like the site linked above better, nor am I saying to use those exact colors or layout. I merely provided it to you to inspire you if you wish to make further changes. My .02, of course.
