Recently, I found another very useful function for Diigo, and that is having it aid me in my study of the Spanish language. I am trying to brush up on my skills in time for a job interview, and am meeting with a friend each week to discuss an article (in Spanish) that we have both read. I am using the Diigo comment tool to translate any words in the passage I don't know. That way, when I reread the text, I don't have to rely on the translation, but can refer to it if needed. It is so convenient, and I can't wait to learn more Spanish using Diigo. Has anyone else found that Diigo has aided them in other ways? Are there other cool features I should know about?
