What?
It's not millions of hits, but traffic is traffic.
Overall, the submission process is somewhat more likely to result in approval because the owners tend to be a little more relaxed, and it is rumored some still accept free submissions thou even if they don't, the price tends to be either considerably more reasonable or a one-time fee, for examples.
Overall, there are 200-300 active ones, likely at least 20-30 will fit your site.
I may recommend you take your time, unless you can spot a fake or bogus directory from a mile away, take 20 minutes and surf the site a bit, to get an idea of its quality, so to speak. Also, read the rules and the closer your site fits both the rules AND the category(ies) available, the better.
Far as what is quality, that you must decide thou in my case I learned it gets better with time.
Good Luck.
p.s.: I am not allowed to give you the url to mine because that would be self-advertising and I am not allowed to tell you said url may be located as close as 1 click away.
BTW. For those that use the previously used directories and are weekend/holiday warriors. Skaffe is having a sale over the New Years weekend of $5 submissions.
