Let it never be said that I can't be shamed into spending precious hours tweaking the code for my site. In addition to finally committing myself to a set of categories and adding them to the sidebar, I've added a toggle feature for several of those sidebar elements, so that I can make my page a little more manageable.
And over the next week or two, I'll probably add back some of the features I've dropped -- the media I'm currently consuming, a second blogroll for sites as opposed to people, etc. Now if I could just develop a toggle feature on my to-do lists, one that would make large sections of said lists disappear...
When you figure out that to-do list toggle, please share it with me! My entire working life is one giant game of whack-a-mole right now.
