I've upgraded the software behind this blog to WordPress 2.5 and (like everyone else I've read who has an opinion) I love it.
Now I just need to figure out how to automate the sections in the sidebar, making them into widgets. Those are modular tools that I can add or remove from a control panel, as opposed to writing them in manually to the template. This will make administration oh-so-much easier and makes WordPress that much more appealing for small site managers.
And in time, I plan to tame the too-long list of categories (which should be for pre-planned structure, like UUA or church administration) by making more use of tags for ad-hoc indexing (like a particular program or interest area).
