THE WASHINGTON TIMES -- Nov 25 -- Tracy has multiple sclerosis. "I went online and I looked under 'disabled dating' and there was nothing," said Tracey, who debuted Special Singles Online in July 2004. Ms. Saks is one of an increasing number of operators of niche dating sites in an industry that ballooned from $50 million in 2000 to an estimated $490 million this year. Even traditional matchmakers are finding their way to the Web. The Right One and Together Dating, an offline matchmaking service, is offering a "hybrid" online dating option, ELove.com. CEO Paul Falzone, said the existence of online dating sites has only boosted business for offline services, which cost $2,000 to $5,000 for a lifetime membership. Offline services charge more because they do more of the work, Mr. Falzone said.
