There are several online dating services out on the Web, but several questions and obstacles should be considered when using an online dating service.

Some people have concerns, such as safety and distance, when it comes to utilizing a dating service on the Internet.

Richard Boyum, of counseling services, said people need to personally meet the person they are dating.

“Sometimes expectations take over,” he said. “We need to see a person.”

Meeting someone online also brings about safety issues.

According to Cupid’s Corner Online Dating Guide, online daters should be anonymous by not giving out personal information and using a nickname, not giving out your real name or address. Another suggestion the Web site gives is to check the service’s privacy policy to avoid “cyber-stalkers”.

Most online relationships don’t work is because of the distance between the persons involved. “Sometimes they are just too far away, they can’t come see you this weekend.”

When people decide to arrange a face-to-face meeting, Cupid’s Corner suggests going somewhere public, in a group, and where you know it is safe.

But just finding that person may be the challenge. Three online dating services are rated below according to the potential they provide.
