On several channels I watch, I've noticed the top comment is always along the lines of "who was here when the video title was XYZ" because you know it's going to change.

Have you noticed that has become more common recently? Because I have. It seems over the past 3/4 months, reload and see a new title happens pretty much daily to me (it also seems to work because sometimes it causes me to click the video I didn't click with the old title).
