For all those who haven't read the article (it was on the front page for a while), here:

Also, for the time being, you can access it at the top panel.
I hope to finish the response by the end of the week (and perhaps even earlier), but the gist of it is that, as much as eroge can do some good for the game industry, it won't be as 'great' as some might hope.
While it will be a rebuttal, I shall state that I do not entirely disagree with Josh's article. Rather, I think that a lot more than just eroge would work wonders for the games industry.
