quality is much more impt that names.... if they choose to invest on sub-domains, why not? but i think the more impt question is.... how abt for deep-links? since sub-domains are technically considered as a separate URL rite?
I for one would do it like this link 1 directory.jodee.biz link 2 directory.jodee.biz/arts_humanities/ and so on
no, what i mean is this: someone submits www.domain.com then submits blog.domain.com as deeplink how?
