I would make and submit one page for each of several main categories, since some attract more traffic than others, and acceptance by link lists can vary by category.
Submit everywhere you can, and wait a month or two, then check your stats...by then, you'll have a really good idea where most of your traffic is coming from... At that point, you can start weeding out the sites that don't send any traffic.
After you know where to submit to to get the best return, then concentrate on making a lot of sites and submitting...but remember to check your traffic stats every couple of months...
Just my 2 cents worth |cool|
