I read a review and saw this quote which I think holds water:

"I believe that by logging into my personality profile questions upped my position. I have come to the conclusion that 29 dimensions is a clever marketing tool and a load of crap"

I do not recommend eHarmony. It is just like all of the other sites except you can't search their profile database like you can on Match.com

It's too bad that 29 discriminating variables don't mean anything if they fail to properly discriminate or have no power to begin with. The 29 dimensions are merely a distraction from the fact that his model, in reality, is a mere marketing tool and based on observations. This guy is a Ph.D. What do Ph.D.s do? They write books, and the site is just a promotional tool for his books. Look at Mr. Warrens' bio, you can buy his books right there on the site.

If Mr. Warren's model is really valid perhaps he could post a link on his personal site to published research papers that outline his methodology and help verify his claim; at least post the results if he does not wish to disclose the details. Of couse, not disclosing your methods is contrary to the whole concept of a Ph.D. publishing so that the theory can be independently tested and verified. Otherwise it is just fluff. All the articles you find on his personal page are non-scientific and none involve the sort of scientific rigor you would associate with a quantitative, personality matching model. I have searched and as far as I can tell, Mr. Warren has never been published in a scholarly journal. If he truly created a valid quant model of relationship compatibility the guy would be the biggest thing since toast and he would at least be cited somewhere. However, it seems that he is more interested in validating his ideology than his model.

The whole service is just a way to promote and attempt to prove Mr. Warrens anecdotal relationship theories and his books on relationship theories full of nothing but casual observations. The entire process is a model based on his books (which have no scales or measures in them. You'd think a guy who invented a model with 29 dimensions would at least have a small interest in the quantitative realm), and the entire site is just an attempt to unscientifically prove a crappy model and promote Mr. Warren's books (which are also anecdotal and non-scientific, like his 29 dimensions).

Mr. Warren's real "29 dimensions" are simply the multiple choice questions and haves/cant's that are mentioned in his books ad nauseam. The 29 dimensions are just marketing fluff used to trick consumers into believing their is a quantitative base to an anecdotal model. Mr. Warren has no published material (in scholarly journals) when it comes to his 29 dimensions.

Join any other dating site. Mr. Warrens says that he is more than just a picture and a paragraph, but his service is nothing but every other dating site plus extra restrictions (no searching, communication stages), more money per month, and some fluff thrown on top to seem like it was made by smart people.

I'm sorry Mr. Warren, but antecdotes do not pass as scientific theory unless you are a scientologist, which we all know you are most definitely not. Your zealous and clever attempts to force-feed us this concept of soulmates, marriage, nuclear family in one month using a flawed model shows how desperately you want it to succeed so that you can use it as anecdotal evidence that enforce your Judeo-Christian views. When it comes down to it, it is STILL about the picture and the paragraph. Buyer beware.
