Agreed - threads will be hijacked regardless of the subject line and I'm not lobbying to try and put an end to that part of forum discussions. That's what makes a forum more interesting than just Googling everything. But a descriptive, more unique than "Just wondering...", subject acts as a better mnemonic to help you remember what's inside even if it does.

Yes, if one sees a thread with a subject that doesn't immediately interest them and they skip it, they run the risk of missing the resulting drift inside. That's a decision everyone has to make on lots of things.:-)
