I know everyone is doing

I know everyone is doing it at the moment, but I’m considering a fairly fundamental redesign here. This site is suffering severe linkrot, the navigation could be improved, the layout is cluttered, the code is a mess (it looks like it has been constantly tweaked and added to, which is exactly the case) and I’m considering switching CMS. Which means taking one of my precious days off and spending it in front of a PC doing nothing but geeky stuff all day long.
Areas that need consideration:

  • tables vs CSS2
  • more easily maintained site elements, especially the lists of links and the about page (PHP?)
  • cleaner design implemented across the entire website (one or two parts, such as the search results page, still use ancient designs)
  • better organisation of content – is an archive that is ordered only by date the best format?
  • improved accessibility
  • continued balance between browser compatibility and standards compliance (there are still a few NN3 users who read this site, and I don’t want to ignore them)

No plans to change the overall content or writing style though. I’ve never really consciously developed a style, it’s just developed in a steady and organic way over the last two and a bit years. Most of the time I like it, occasionally it bores even me.
Ultimately, this is my site to do with as I wish. But you are welcome to throw in any (constructive) thoughts and suggestions. Which I am free to ignore if I so wish.
Why is it that I get a feeling that this may take more than a single day to implement?
