After 4 years I'd pretty much decided on a new, clean blog design. Picked the template, tweaked as required, new menus, listings etc, new colours.
Sharp, clean, fresh.
Things have moved on somewhat with blogger 2.0. It's all coded in xtml and no longer html. Haloscan comments didn't get upgraded with the transfer to the new template and wouldn't work when edited in (and I'm not such a dummy that I can find the head etc of an XTML doc).
So no new blog layout yet. Maybe manana. Any blog-jockeys out there are welcome to suggest a solution.
