Too American for what?
Its an American based English language website that attracts English speakers from around the globe. Which has the effect of skewing towards the English speaking nations of the world -the largest of which is the USA.
So it biased towards the folks who use the site - Americans. And secondarily for Brits and other Anglosphere countries (Canada, NZ, Aus, South Africa, etc). So its just right for the folks who use it.
There are a fair number of nonAngloshere users from Europe, Asia, the middle east, and Latin America. Asian Indians have come and gone. We had one young lady from South Korea (who seems to have gone awol).
The Scandanavian countries , and Finland, are well represented despite their small populations.
