Which language is best when using Twitter?

Certain languages are more conducive to tweeting than others, according to a recent article in The Economist. Chinese and Japanese are especially useful for micro-blogging due to their inherent brevity relative to other languages. (Twitter is blocked in China.) Those who tweet in Arabic and Korean can also make their micro-posts relatively concise.

Romance languages fare less well: more characters are required to convey a given message. However, shortcuts and abbreviations abound, and English in particular allows its speakers (tweeters?) to drop subject pronouns, abbreviate, and use acronyms freely.
