LOL, I can't help but laugh... I am doing link submission and I stumbled into a directory where I hardly find a category to add my site... Here is the internet category... tell me what you think.. http://directory.pageindex.info/category-8.html
Thats because its in another language ... at least thats how it looks . Anyway, not all directories have over 700 categories like dmoz, so chose them wisely .
I believe its auto approve on categories too, ive come across many running that script, can put in anything and it wont get checked, add a category exactly matching your site. Not saying thats good but its the owners responsibility to check it more.
