Little / no use of vosotro/as
Is this specifically aimed at Latin American Spanish? I've noticed there is basically no use of vosotros and vosotras and their verbal conjugations at all - as well as much more use of usted / ustedes than you would normally use in Spain. My girlfriend commented on this when I showed her this website in Spain and told me I shouldn't even be using the website because of the bias on Latin Spanish. Can't we at least have an option somewhere to use vosotro/as in preference to usted/ustedes. Or just include both to suit everybody. Something of that kind. It's frustrating that I'm not learning extremely "vais", "sois", etc.
This has been commented on quite a few times. I agree with caiser that it's probably an overreaction to simply not use the site at all. The great majority of the Spanish vocabulary and grammar you'll learn is universal. And, as caiser also noted, it's not as though Spaniards won't have a clue what you're saying if you use slightly different words. That's like implying that an American wouldn't understand what a British person was talking about if she used the word 'whilst' instead of 'while.' I was taught Latin American Spanish (mainly Mexican), but had no problem being understood as an exchange student in Spain-- though after a few days, my host sister did teach me a few different terms. :)
That said, while it's not the end of the world to not know/use vosotros, I agree that I would very much like to see it added. Perhaps there could be a profile setting to either include or exclude it from practice questions? I don't think it would take all that much effort on the part of the developers, and it would give people who want to learn it some much-needed practice.
Say your girlfriend that it's exagerated to say you that you must leave the website. Force you to use the forms used in Spain, the system allow them. I learn the British English and I am reinforcing it here, and I say you that I am going to continue using the site even they are teaching me the American English. I am from Spain and I can understand competely to all the Hispanic American.
