Firstly, you should look harder. You may be right, but then again you may be simply looking in all the wrong places. They won't all be found in directory lists, or even with the method of searching for keyword + submit/add url/directory. The more useful ones may well be finding other ways of reaching their intended audience.

Secondly, how narrow is your niche? You more specialised you go, the more useless your submission form will be, because you will tend to get a lot of off-topic suggestions. But highly specialised lists are also more useful to visitors.

It's more work than most people realise to compile a good directory. Dip your toes in the water by compiling a categorised list of a hundred or so websites, with short descriptions, and just post it up somewhere. If you find you enjoy this kind of thing, you can use this to seed a larger directory, but if not then you will at least have learnt something, and this list itself may attract some traffic.
