Marc, a linguistics graduate from Quebec, has created this “complete method to learn Spanish.” I don’t think it is very complete and it is obvious that it was written by someone who studied linguistics. For me it overly complicates things and claims that Spanish is a difficult language to learn, when in fact I think it is not. I also think step 2 (choose which language variety to learn) is really only relevant for certain languages like Arabic or Chinese, where dialects vary greatly. For something like Spanish, I think the differences are interesting but not severely limiting and a smattering of all is good to aim for. But hey, that’s just my two cents; give it a read yourself and see if you agree or disagree.
