I change the subject line frequently, so I apologize if that annoys you, Todd. You don’t seem cranky at all, but I have to disagree with you, and would not want to see locked subject lines.
1. There are benefits from changing subject lines. I don’t always have the time to look at every post in a thread, so if someone takes the discussion in a direction that sounds interesting, I like to know that. Similarly, I appreciate it when someone simply wants to say “Thanks” or “problem solved” and puts those words in the subject line, thereby saving me the small slice of time it would take to click and read.
2. There’s no substantive negative from changing subject lines. Visually, the way the COW lays out threads makes it quite easy to tell which thread a given post belongs to. Being able to scan a thread and seeing in a subject line a new twist to the discussion is like chapter headings in a book – very useful.
3. The alternative of opening up new but closely-related threads would make the busier COW forums more time-consuming to plow through.
Where I might agree with Todd: gratuitous subject line changes. But I can’t say that’s ever really annoyed me.
