One of the best ways to improve your Japanese knowledge is immersion. For those of readers who have achieved symbiosis with our laptops and smart phones, I recommend setting as many things as you can to Japanese (within reason for your level): apps, websites, even the language settings for your cell phone. As for your social media, in this week’s fun link, Daniel Morales discusses the vocabulary used on Japanese-language facebook in his special to The Japan Times “Ii ne! Facebook is a perfect place for Japanese immersion.”
Personally, I much prefer いいね!-ing something to “liking” it; answering 「今何してる?」 for an update makes more sense than “What’s on your mind?” (and is maybe less likely to cause confusion for facebook newbies). What technology have you set to Japanese language settings for studying?
