>> Unless you have something unique. So what's unique? If you're an Orange Hand Goo site, maybe you start handling all sorts of cleaning products from multiple vendors, and offer unique combinations of products. Of course, 45 other sites will likely copy you in 2 months... <<
Or you could write (and copyright), say, a history of Orange Hand Goo, and its derivation from clear hand goo by the addition of OranjStuf. Not everything has to be about selling things, even on a shopping site. Adding unique informational content is a little extra effort, but it is one way of increasing the probability of an ODP listing, and as a bonus, can bring extra traffic to your site (e.g. from Orange Hand Goo history buffs). It's not just ODP editors who appreciate unique content; "regular" people do, too.
