I think "program line" is a downright unarguably terrible title. It doesn't say clearly what the node is about.
As you say, that's what you think. You're wrong on at least one point though... I'll argue it. As I said in my reply to swampyankee below, I knew what the node was about when I read the title. So, there's a little empirical evidence to counter your opinion that the title doesn't (didn't) say clearly what the node is about.
As I also said to swampyankee, the fact that you think it is a poor node title doesn't automatically indicate an absolute quality about the title. It isn't a title that works for you, but there may be many people that it does work for. In the long run, almost every question will be asked with a wide variety of titles and complete coverage will be the natural result. That is, if we don't go unnecessarily mucking with those titles.
