That, or I’m repulsive in some way.

I know you're joking, but I'd like to point out that the problem is probably better defined as 'not distinctive enough'. By that I don't mean to say that you are in any way an uninteresting person (no-no-no!), only saying that the internet dating game is one of marketing. If you aren't using the correct strategies, you won't get the results you want.
You could study marketing and apply it to human interaction... or you could pay these people to show you how it's done:

http://www.insiderinternetdating.com/
I saw both of these people speak at a seminar about on-line dating, although I have not used their services (presently happy in current situation ).

However, if you aren't skilled in dating in general, the on-line thing will only open the door. So...

* A Caveat *
I appologize in advance for the 'hukster-ish' style of some of the sites I've linked here. Once you get beyond that and into the deeper training packages, you'll find a wealth of knowledge that has a good chance of changing your outlook- even beyond dating.
I've met the people behind the sites and will tell you that in my opinion they are people of great integrity.

In response to the original post, I say ask not if internet dating works; ask how internet dating can work for you.
