English to English is The Guardian New York newsroom's new Tumblr blog which attempts to chronicle and catalogue (catalog?) UK-US cultural differences, poke fun at the ‘special’ relationship and build a living glossary of news, slang and pop culture terms. Here's a video from the blog.
The English to English blog's been going for just over a month, and there's already a lot of really interesting content. Readers can Request/Submit a translation, and tweet using the hashtag #eng2eng, but it's a pity that there is no "Comment" feature on the blog where you can contribute ideas. One to follow all the same.
