Doing payments for articles, expenses, and a few articles. This is definitely a paperwork day. As much as I like the writing and other work on the site, and as much as I enjoyed DBA work, I hate paperwork.
We've automated quite a few things, but some things always seem to fall through the cracks. Ideally we'd have some sort of real-time application to enter expenses into, but I'd probably forget to take time to do that. At Peoplesoft we could read in our AmEx card expenses and mark them as corporate or personal, but that failed on a regular basis and didn't seem to save time.
There is probably only a limited amount of stuff that can really be done with this since it's so ad hoc and there should be some sort of control to prevent abuse of the system.
