Harder, Better, Faster, Stronger (5-/-0/2008)
I'm about half-way into my rewrite of the site code, and have plenty of gnarly little optimisations to try. I want to add a layer of caching (my webhost provides memcached, so that'll be my choice made for me), and then I want to try and get to an A rating in ySlow. I'm not far off it at the moment, and I'm not sure if I can be bothered moving the static files (sprites, css and js files) to a CDN. I'm interested in the Amazon S3 service, or something free like the Coral Distribution Network.
I'm about 25% of the way through the redesign (actually, re-hashing an old redesign that never saw the light of day), and will trawl the web, and design books, for inspiration over the rest of the week.
