I think the issue with language specific sites is that the majority of the internet into this sort of thing already speak English. It might be a false assumption, but it seems that the educated people interested in the sort of thing that goes on here and on reddit are, in the majority, English speakers, even if it's not their first language. Sites that cater to a "lower intelligence audience" (without trying to sound condescending) will have a market because the people in their audience won't be English speakers and won't want to adapt, but in the business and technology world being without English is a pretty big hinderance. Although it'd be interesting to be proven wrong, I wonder if there are any already successfully non-English startups around (that focus on technology).
