For a while I have watched dating sites subdivide their possible audiences like mitochondria in a heated petrie dish. In the beginning there was Match.com. Then dating sites subdivided by religious affiliation (e.g. JDate). Then there was demographic subdivision (e.g. the Onion personals). And finally we've gotten all the way down to author-centric subdivisions. My recent discovery bears this out: the Atlas Shrugged Dating Site.
This is simply to good an example of juxtaposing Chris' Long Tail with Bob's Network Law to pass up mentioning. So in the spirit of naming things, I am going to propose Robertson's Law (also known now as "John Galt's Law"):
The value of a social network is propotional to the square of the number of users of the system multiplied by the inverse of the social networks rank amongst similarly themed social networks.
In other words, the social network value of 100,000 people connected to the "Da Vinci Code Dating Site" is much less valuable than 100 people connected to the "Atlas Shrugged Data Site" assuming that Atlas Shrugged is more than 1000 times less popular than The Da Vinci Code.
All joking aside, I think I may be onto something here. In any event, I hope the process of dating site subdivision continues because eventually someone will create the extremely niche oriented "Niel Robertson Dating Site" that only includes two members. Wouldn't that be nice. Fingers crossed!
