1. Video and Podcast Magazine (blog.makezine.com/podcast): There are many DIY projects suitable for weekends, some are quite bold, and others are rather humorous.
2. Orwell Diaries (orwelldiaries.wordpress.com): George Orwell's diaries serialized in blog form, covering his personal life and political views. These diaries were written approximately 70 years ago.
3. iTunes (apple.com/itunes): Everything on the site is free, and the most surprising part is that it offers lecture recordings from the world's most prestigious academic institutions (Yale University, The Museum of Modern Art in New York, Oxford University, Tate Gallery).
4. Mysterious Maps (atlasobscura.com): Focused on strange and unusual places, it has no intention of becoming a traditional travel guidebook.
