Can you suggest any blogs, email subscriptions, twitter feeds etc. of German words, phrases, or quotes of the day?
I'm looking for something that will present me daily with a single random word/phrase/quote. It could be an email or a twitter feed (or some similar asynchronous presentation). For example, in English there's a site called A Word A Day. You can visit to get a word, or you can subscribe to get an email of that word. I'm looking for something similar but for German.
If you can please give links and your assessment of the words/phrases.
Any and all kinds are welcome. Famous quotes from authors, vocabulary for school children, slang expressions, whatever.
Any medium is OK. Twitter feed, email, whatever (even paper mail, but online is best).
(any suggestions on refining this question to make it reopenable are welcome)
