I added indexes by date (in the right column) to allow searching articles by year, or a combination of year and month. It didn't take too much work, and seems to be a nice addition to the blog. I also reduced the font size on the right a bit. It's starting to get a bit cluttered, so I may want to rethink how I display the latest posts and tags.
Of course, this blog is purely a hobby in of itself, so I may want to actually write some content eventually.
