I don't remember how Bueno, Entonces... (which can be translated as "Well, then...") first caught my eye, but once I took a look at their Facebook page I was hooked. It's my understanding that they offer a full language-learning system--not covered in this Bueno, Entonces... review--but the bite-size facebook version, with short video lessons or illustrated tutorials on topics that range from hilarious to vocabulary so realistic it's borderline inappropriate, makes a great supplement to any Spanish language learning program. The greatest appeal of the Bueno, Entonces... Facebook page is that it's short, quick, and immenently useful. Even if you're not planning on using the sometimes risqué, occasionally offensive vocabulary you learn here, you'll probably want to be able to understand it if you ever hear it.
By the way, you don't need a Facebook account to view the Bueno, Entonces... Facebook page; just click the link above.
