While I need to make some minor changes to it (like providing external options to choose between the long and short version, as the "Enter blahblahblah within 20 seconds" approach doesn't work in a cron job), I know I need to make one major change: making the script better-written.

Long scripts may be the entire problem right there. A lot of the "masterful" Ruby I have seen is really brief, not long at all. If a method takes more than a handful of lines, it gets refactored into two or more shorter methods, these get organized into sensibly-designed classes, and no single script gets responsibility for more than one thing. I am in no way qualified to write like this, but I have seen it enough times to know that it's what I should be reaching for in my own work. Open up @tenderlove's CSSPool project, which parses CSS into Ruby objects. It's pretty hard to find a method more than 4 lines long anywhere within it.
