Well I can give my experience if anyone is interested.
I wasn't looking for a partner, just for friendship with people with similar interests, and that was why I put my email in a list on a certain site, that was in May 2006. In September of the same year I got a reply [the only one I ever got, and eventually deleted my email adress from the list later] from a guy and it's a wonderful relationship now. We have met in person too but for now the relationship is still long distance because it's complicated with money and practical life. But we are sure we belong together, it is all quite miraculous, the way we met and how it turned out. We are bothe Christians and serious and comitted in this relationship.
So you don't have to dismiss this; because you can never know when and how you'll meet the right one for you. The internet is very helpful with it, it opens possibilities to get to know people you otherwise would never get to know. If you keep meeting the same circle of people in your city, you may think there's noone for you. But maybe the perfect person for you lives somewhere further, and in that case it's surely worth it! [Even when, practically and financially, it can be harder than with someone who lives close to you. But it all depends on the couple and if they really want to make it work.]
