Update Jan. 1, 2011:
Starting today, I’m using a new theme I’ve crafted, which I am calling Goshen. It’s designed to be minimal but readable. The theme I was using previously, Porfolio_AD, is going to rest comfortably on a beach somewhere and probably won’t be coming out of retirement any time soon. You can still download it — I know of one person who actually did implement it on a site, much to my shock — and play to your heart’s content.
I make no claim to having any design sense, but if you like the WordPress theme I made for my site, you’re welcome to it. Grab it right here.
Portfolio AD is a one-column theme with a two-column sidebar. Both columns in the sidebar can display widgets. The header is a modification of the well-worn Hemingway theme, and the rest is my take-off of a site built via this tutorial from WPDesigner.com. It works fine with WordPress 3.0.
What you see here is the result of constant tinkering. I coded up a theme of my own to learn more about what WordPress can do, and in the process I have learned tons about CSS, HTML, web hosting and content management systems in general. If you have the time, it’s well worth the investment.
Use the theme as a starting point for your own tinkering and have fun!
