Modern Wedding Vows - Seriously, WTF?

I am slightly completely obsessed with reality wedding programs.  My favorite programs are Four Weddings, Say Yes to the Dress and that wedding makeover show with David Tutera. I can't stand Bridezillas for more than 10 minutes or so because it's usually just a white trash train wreck but it interests me to see how weddings have changed over the last 10 years since I got married (i.e., the pre-Pinterest days) and the boom of the wedding business.

Judging other people's weddings?  Yes, please.

One of the main trends I have noticed in all of these shows is that everyone, and I do mean everyone, writes their own vows now.  In fact, on Four Weddings, you should pretty much expect to get dinged if you are "too lazy" to write your own vows and go with traditional wedding vows.  I do not get this phenomenon.  I'm sorry and I hate to be snarky but most people really aren't qualified to write anything  good or meaningful for their vows.  All of the ones I have seen come out corny, silly, overly emotional and saccharine or just plain bad.  The worst are the people that try to sing their vows to each other.  Please,  don't.  Seriously, stop it.

Steve and I were married in the church so we used the traditional vows from the Book of Common Prayer.  To be honest, the idea of writing our own vows never really occurred to us except as maybe a joke.  Why mess with something that isn't broken?  We never thought we could improve on the traditional vows so we left them as-is. I understand that if you're having a non-denominational wedding you probably want to revise the vows so they are non-religious but the basic gist of getting married is still there.  However, I have personally witnessed some real train wrecks of vows.  One of the worst were some friends of ours who we love dearly but in his vows the groom actually thanked his bride for "liking to watch television" as much as he did and for "learning to make brownies."  Really?  In your wedding vows?

Seriously, why and how did this trend become so ubiquitous?  I think it stems from everyone's need to "personalize" their wedding and "make it their own" but isn't that what the venue, food, cake, signature cocktail, decorations, place settings, dresses, tuxes, flowers, music and entertainment is for?  I guess I'm just a fuddy-duddy.
