I discovered this site recently while browsing through open DNS. There appears to be a large amount of content available from this site. I have not had the time to do an in-depth study of the site contents. I was impressed with the Atlas section of the site. The site also has a large number of language tools available. The amount of time I have spent has only tweaked my interest in what this site has to offer. I would be very curious if any of you have investigated the site in more detail.
