The entry is mostly the familiar dogma, tired and tiresome ("In the harsh world of anime business, apparently a DVD only sells as well as the amount of scantily-clad females an artist can squeeze on to the cover" -- real quote! at least we were spared bashing of Naruto), but contains an important suggestion:

So, going back to Alex’s question, for the anime fan in 2008, is it essential to watch online anime? For me, it is. When so much excellent anime continues to be ignored (or terminally delayed) in favor of poor quality, superficial disappointments, the internet is, quite simply, our only option.

It was long held by its enthusiasts that the online distribution promises an infinite stratification and specialization, as much as the production capacity supports it. Every lover of Kaiba should be able to buy it, and its every maker becomes appropriately compensated.

However, the vision of "people .. fall[ing] in love with it, if they could just get a chance to see it on TV" runs across one little problem: the non-anime hoi polloi do not want Kaiba either. And making anime is expensive. So, all that the power of Internet really is doing is making marginal[ized] art available where it previously was not. Kaiba is going to fight for the mindshare of the people who watch gay ballet.

Mushishi is a bad example because it's readily available to the masses in the Anglosphere.

UPDATE: Paul refines the argument in a follow-up comment, including:

Mushishi is a good example of world-class anime that should be on TV but isn’t. I used it because I’m looking at this problem from the perspective of trying to attract new fans to anime. What’s the typical ‘gate way’ drug of most anime fans? Pokemon, Naruto, DBZ. Fair enough, but from a constructive point of view, may be the industry should be looking at new ways of attracting people who aren’t into that kind of thing?

I am almost certain that Mushishi was in fact broadcast by Cartoon Network, but perhaps I'm mistaken after all. My family has seen it on rental DVDs from Netflix. It is quite true that it's liked by a different set of people from stereotypical anime fans. The English dub was quite good, BTW, which must've helped.
