Yes, many sites -- Google adwords and adsense, Overture, Yahoo, Looksmart -- all offer "paid" links and fast service. If that's what you want, there they are! The ODP doesn't need to offer that service: it's already covered, and there's no reason to suppose that we could do it any better than the others. (Actually, it's even worse than that: when the ODP was created, some of the others were offering free directory listings. The founders thought a community of amateurs could do that better, and they've been proven right. The flip side of that is that amateurs tend to resent other people being paid for the same work they do outside their favorite categories "for the good of the directory." It's very likely that any attempt to introduce paid inclusion would have a catastrophic effect on the morale and morality of the community.) So we don't try: we focus on a different mission.
Like all web hosting services, you offer a grab-bag of "other internet related services". Everyone offers a slightly different bag, but they are so many such sites, and they offer so many different little services for which we have categories (intended for specialists) that it is impractical to list each one under all the services. So our guideline is that such sites are listed once, with the description mentioning the range of services. (We tried it the other way, and it really really didn't work: there may even be some listings that are holdovers from those dark days. But we won't go back.)
What we DO list is customers of website hosts -- whether or not they have their own domain name. Google newsgroups, Yahoo Geocities personal sites or Yahoo shops can all be listed -- just like personal, community, or business shops that have their own domain name so we don't know who their website host is.
And, of course, Google and Yahoo both offer substantial amounts of unique content -- I think both of them would rank among the half-dozen most content-rich sites on the web. And for both of them, "hosting" is a late and minor addition (through corporate acquisition) to what was already a rich set of offerings of internally generated content.
I hope that clears up some of the confusion.
