Online dating was once regarded as a bit strange, and possibly a last resort of the lonely. Now, online dating sites and social networking are downright commonplace! Thousands of people have joined eHarmony and, and posted a profile on Yahoo Personals. Social networking sites that are more than dating services (such as Friendster and Facebook) are quite popular. But the size of those pools can be intimidating. You can narrow your search for a date by seeking out a niche service, a dating service that caters to people who are like you.

435_golfcouple3.jpg was launched in 2004 by Scott Kroeger, who set up some of his golfing friends and decided the golf community needed a dating service.

The philosophy behind is simple: Golf is the perfect first date. Why? It's a sport men and women can enjoy playing together. The sport provides an instantaneous icebreaker—a common interest that two people can discuss. Golf is a relaxing, safe, outdoor activity that provides ample opportunities for socializing between shots. What is more, after nine or 18 holes, a round of golf comes to an end—if two people are not compatible, the end of the round is the end of the date.

Registration is free. The same company also runs
Golf may be a great first date, but scuba diving is a serious and expensive hobby that requires training and planning, and often a lot of traveling. It makes sense to seek out a partner who also dives, or at least understands the time commitment diving requires. offers free registration for those who want to meet divers, but the "news" page hasn't been updated since 2003.
When you have serious political convictions, it's hard to click with someone who doesn't share your views. Enter the political dating sites.

In researching this article, I ran into some sites that I didn't include because they didn't seem to be quite what they appeared. There are two schools of thought on selecting a dating service. One says "you get what you pay for" and why should you go for a partner who won't pay for a premium dating site. The other says if you must pay before you can see what you're getting, then you may be burned. However, some sites require registration only for the privacy of their members. Before signing up for any dating service, do some research on their methods, reputation, and policies.
