While it's not the same as emo, the goth scene has many common interests, styles, and some musical similarities.That's why sites like Emo Dating Site shows "Goth Greeting Cards" and "Gothic" blogs and forums on their sidebar.
People tend to wear tight jeans and small, tight, often vintage T-shirts or shirts of punk banks. Chuck Taylors are almost a required part of the uniform, as are black, studded belts and black-rimmed glasses.
Emo love is different from the normal dating scene mostly because of the emotional quality of the relationship and the characteristics of the emo personality.
Like Less Than Jake and Silverstein and want to show off your ink? Club Emo also has quite a few members and a more designed interface, including the ability to send members little "flirts" just to let them know you're interested.
However, you can't do everything on the site for free like you can on Alt Hookups; you need to pay a fee in order to send messages to other members (though you can upload photos and have them message you).
"Emo" is short for "emotional," and by that criteria almost anyone looking for love would fall into the category.
