That title changes the entire scope of the thread. I don't really have a problem with that, but if/when I make that kind of change, I check the first post to make sure it follows the intent of what the OP wanted. In this case, it does not. I'm sure there's a lot of posts in there that are off-topic to the original intent, but making this change would be somewhat like saying it's okay to be off topic, we'll just fix the title at a later date.
In short, I don't want to "reward" a bunch of thread-hijacking douche bags by changing this title (intent) on this particular thread.
