Is Marriage Obsolete?

To start, I believe in fate, love, romance, and all the things some people like to explain away. But, I can't say in all honesty that certain things today don't create some sort of doubt in my mind; I've just gotten very good at pushing the questions away, at least for a time. 
Recently, I saw a poll showing how roughly 60% of people now believe marriage is becoming obsolete. 
Then, while contemplating an excursion in online dating, I found an article where the founder of e-Harmony basically says we may no longer need marriage.  Of course, he does go on to say that marriage can be a beautiful, fulfilling experience if people took the time to select a marriage partner. This makes sense, given how many people we see jumping into marriage at the drop of a dime, only to hop right back out in the not-so-distant future. 
Do I need to rethink this marriage thing? Could I?
I get that it's just a piece of paper and it shouldn't matter when it comes to love.  But, well, I just can't accept that...not for me.  Maybe I'm too old-fashioned for my own good because I still believe in true love and marriage. I know the world has changed; I understand the dynamics of relationships have changed.  And I'm acutely aware that I was, in all likelihood, born in the wrong era.  Still, I love believing in what doesn't seem possible. 
Here's the question burning my brain cells:  If the majority of the world views marriage as wholly unnecessary, how does someone like me ever hope to find a man in this great big cynical world who still believes in a little thing called vows?
