My collection of Mandarin Chinese links for March 13th through April 29th:

• Leiden Weibo Corpus – The Leiden Weibo Corpus, which consists of 5,103,566 messages posted on Sina Weibo in January 2012.
• AllSet Learning Pinyin for the iPad – The AllSet Learning Pinyin chart for the iPad makes pinyin study easy and enjoyable. The interface is simple, clean, and ad-free. Every pinyin syllable has audio (just tap on a syllable to hear a native speaker recording), and toggling between the four different tones of Mandarin Chinese is easy.
• Introducing HanziJS – Chinese characters consist of radicals, which are the fundamental building blocks of each character. However, until now there was no way to automatically dissect them without consulting dictionaries, random websites and other untrustworthy sources.
• ‘Beijing Beijing’ by Wang Feng – Music video with lyrics in Chinese, Pinyin and English
• Chinese Learner Interview Series: Kellen Parker – Kellen is a published linguist with a background in linguistics and philosophy. He spent time wrestling with languages like Albanian and Arabic before coming to China and re-focusing his efforts on Mandarin.
