• Related Posts should show up to 5 related posts without too many false positives on single article pages. I like how this plugin scores posts on relativity and that I can set it to show nothing when no posts are related, which keeps the interface clutter to a minimum.
• A single easy recognisable block of Google Adsense adverts has been added to single articles. You won’t see it if you have Adblock Plus installed like myself, but it should give helpful suggestions on articles with a single subject and support hosting costs in the process.
• Template tweak: Moved post-meta-information from under the title to the footer (tag/cat info) so that the header is better connected with the body of the post. There’s enough clutter on other sites.
• I’ve visually combined  categories and tags underneath articles. Category are used for url purposes and tags  to facilitate cross linking of subjects. No need for two lists.
• I added a tagcloud to the site so you can browse the site and discover some other articles. I don’t think browsing by time and month is useful to many people so that’s been removed from the site. The only concern I have at the moment is that the cloud would grow to too big a list, so in the future I might just show the top 7 tags used. For now that’s not a problem.
• PHP Speedy. This is the most important reason why the site is so snippy.

There’s more but I’ll save them for another time.
