<p>According to Nikkei, Line, a popular messaging and call service, intends to go public in 2014 on the Tokyo stock exchange. The company is expected to go public at a valuation between $800 million USD and $1 billion.</p><p>According to Serkan Toto, Line has 270 million registered users. It isn't clear what percentage of that user base is active on a monthly basis. Twitter, a company that is also set to go public shortly, has around 230 million monthly active users.

We can't be too perfectly sure, but it would seem that Twitter is being valued much higher on a per-user basis.</p><p>Line as a company has been at the forefront of the rising profile of so-called 'over-the-top' (OTT) messaging services that have quickly grown in recent years. Others include Viber and KakaoTalk.
