eHarmony? It can't be real science.

Some people have asked me why I didn't sign up for eHarmony, since I've basically signed up everywhere else.  I have done eHarmony before though, on one of those free trial weekends. After the painful process of answering all their personality questions, I was hoping they would deliver some really accurate matches.  That's far from what happened. 

Unless their 'scientific' process knows something I don't, I'm pretty sure I'm not meant to end up with toothless, gold chain-wearing, construction workers from Buffalo.  (Like this stock photo model, but with more visible chest hair.)

Am I kind of a snob?  Yes -- I totally admit it.  But more importantly, what would I have in common with that person?  Distance aside, I don't know how I could make it work with someone who doesn't value education in the same way I do.  I'm young and ambitious, and I might want to do a PhD someday.  Someone whose dating profile is poorly written (and uses LOL-speak) says to me that they aren't going to care about life-long learning and self-improvement.  Am I wrong?  You can yell at me in the comments.
