Chinese Twitter rival Weibo may float in the US, according to report

China’s Sina, proprietor of the highly popular Weibo, is reportedly preparing to float the microblogging platform as a spinoff on the New York Stock Exchange. According to a Financial Times piece on Monday, Weibo may be worth over $4 billion at the moment, and Sina has hired Goldman Sachs and Credit Suisse to manage the flotation. Alibaba, the Chinese e-commerce giant that has an 18 percent stake in Weibo, is apparently also planning an IPO, and the country’s Tencent, which produces the WeChat app that rivals both WhatsApp and Weibo, is also doing well for itself at the moment.

At the very least, it should be much more consistent and transparent about its API usage policies, according to 79 percent of the tech audience we surveyed. I’m a little less worried that Twitter has done itself serious damage than a lot of the vocal digerati. After all, the company is less dependent on third-party apps for generating usage than other platforms for, for example, gaming. The companies it needs to coddle are the ones doing analytics, marketing services, and data packaging. And media companies. Take a look at our Flash Analysis, that also examines Twitter’s overall prospects, potential revenue opportunities, and role in the industry, and tell us what you think.

Facebook has nothing to fear, except itself

According to Edward Aten, founder of Swift.fm, Facebook is recreating and competing with nearly every significant Internet product of the last few years.

Who’s winning in Twitter photos? Hint: Not Yfrog or Lockerz

When Twitter debuted its native photo-sharing feature earlier this year, some people worried that it would harm the existing ecosystem of third-party photo sharing apps. New data indicates that those concerns were well justified: Twitter now powers 45 percent of the photos shared on its site.
