@ Minnie Cat... I was wondering the same thing!! RU-vid was launched in 2005. Perhaps, by 2012, they were hitting their stride in popularity. By 2014, 300 hours of videos were being uploaded every minute! That was also the same year that RU-vid got a new CEO and started to make significant operating changes. Perhaps that has contributed to why you don't see as many uploaded proposal videos. Plus, it has logically become more difficult to create original-thought ideas. Anyway, someday all this will be taught as history in college media courses (and, we were there!).
I LOVED the singing proposal in the bar. I would do that. I proposed to my wife (ex-wife now) at karaoke. I am now seriously thinking of proposing to someone I have been in a relationship with. I love this idea and I can sing.
