The appearance of this Web site in style and formatting was updated a couple weeks back and I kept adding new content regularly. The Journal section for instance had a new content area added recently, focusing on Mac Tips and more Arduino related content was integrated into the Embedded Systems area of the site. However, the site hadn't been seen a lot of improvements, when it came to functionality.
Finally, I have taken the time to add a submit to digg.com link into my homegrown PHP-based blogging system and also added a cool photo-viewer, pulling my own photos from flickr.

The search functionality of the site is provided by www.google.com/search and since recommended and demo-ed by Bob, I also use their Google Analytics service to monitor the usage of my Websites, which required only adding a couple lines of Java Script code into the pages' footer-template.
Adding the "Submit story to digg.com" functionality was done in pretty much the same way how search works, but instead of an HTTP GET through an HTML form submission, digg simply uses an HTML link. More details can be found at http://digg.com/tools/integrate#3

Integration with flickr was even easier. I used PSTAM's instructions to put his cool flash-based flickrslidr photo viewer on the site, looping through photos I had already posted on flickr.
Nothing earthshaking, I know. Still, even small improvements like these make the site more useful, at least for myself.
