I would say almost none of our users are Spanish and English professors (presumably they speak both languages quite well ;)). The idea was to get them to use the tool in their classrooms, where their students would be the users. They would have special accounts that would allow them to monitor their students use of the site without actually participating. We did (and still occasionally do) run surveys and ask for member feedback. The feedback was great, and we made a lot of changes to the site based on that. I'm not saying that there isn't a way to monetize the site, I'm just saying that our two main ideas (ad revenue and a teacher tool didn't work out).
