Ryan of WPCandy has put together a massive list of WordPress theme frameworks. I must this is something we’ve been hoping to look at in more detail.
It’s a bloody good list and one that I can think we’ll definitely be digging into a little deeper in the near future. I’ve been doing a lot of work with Genesis recently and am getting a good feel for it’s strengths and weaknesses. I’d love to see a WordPress Theme Framework matrix comparing frameworks in detail.
Perhaps I’ve just given myself another weekend project 🙂
