Asian Audio-based Micro-blogging Service, Bubbly, Goes Global
Bubbly is a Twitter-like service with voice updates on top of text.

Bubbly, a popular micro-blogging service in Asia, is now a global service and was released in the U.S. App Store on April 11th. Unlike Twitter and its 140 character limit, Bubbly users have the option of posting audio or text updates. The service includes “like” and commenting features similar to Facebook.
Voice posts are the driving feature of Bubbly. Users are encouraged to use the audio option when posting to convey the emotion and feeling behind what they’d like to say. I’ve grown particularly accustomed to the fact that sarcasm and irony aren’t always apparent in a text-only platform. Something like Bubbly remedies that confusion.
The service has a strange in-app purchase option. To unlock access to celebrity Bubbly-ers (Bubblers?...Bubbly users), users must pay $2.99 as an in-app purchase. I’m not sure any other service has ever done something like this. I’m trying to imagine Twitter being free, but needing to pay for popular users.
Bubbly has reached 16 million users (1 million just in the last month). On average, users post three times per day and 75% of that content are audio posts. Bubbly is a free service (except for the in-app purchase for premium user access) and the app is available to download for free.
