Stink fetish dating site
You simply flipped a coin, or you could sign up for both to find out which was the right site for you.
When your interests aren't as popular as say, your local sports team, and you don't know anyone in your area who you can talk to about your favorite TV shows, bands, computer programming language, etc.
So instead of potentially making things awkward in your TNG community, you can simply look to find a date from a local database of geeks who you know for a fact are interested in hooking up with other geeks (like you) in your area.

There are lots of different ways to go about deciding which ones are best for you.
Maybe you want to sign-up for the geek dating site that has the most single geeks in your area.
