Rex Isenberg, a 24-year-old classical composer from New York City, met his "wonderful boyfriend" of more than a year on J-Date."I was skeptical at first, but [my cousin] persuaded me to do it by telling me that she met her husband on J-Date, and that they have been happily married for nearly 10 years," he said.

Dating sites don't have "published, peer-reviewed papers" to explain their methodology, and they do not explain in sufficient detail how people are matched, said the researchers."There is no particular reason for people to use sites that charge a lot of money to offer something they cannot deliver," said co-author Harry Reis, a nationally known relationship expert and professor of psychology at the University of Rochester.

However, he said online dating does provide wider opportunities to meet people."The Internet holds great promise for helping adults form healthy and supportive romantic partnerships, and those relationships are one of the best predictors of emotional and physical health," he said.

"To make matters worse, the restaurant we went to was awful."But later they bonded at a live jazz club and when Katz was transferred to Seattle for a medical residency, her fiance eventually quit his job and joined her.

But by 2005, 37 percent of Internet users said they had dated someone they'd met online.

The review also noted that men were still the aggressors when it came to dating, at least online.

And don't look at more than a "handful" of profiles in a given city.

"With 250 profiles to go through in 20 minutes, you can't have a check list," said Reiss.
