An anonymous reader writes: What happens when the Chinese government drastically restricts the type of speech that can be used in their country's most popular public forum? Users start migrating to more private options, naturally. Microblogging service Sina Weibo is bleeding users, while the semiprivate WeChat is growing expansively. It's growing so quickly that the government is stepping up its efforts to monitor and delete conversations that don't meet its exacting standards. The site's posting rules have developed in an interesting way, given the lack of free speech: "WeChat allows the creation of public accounts that anyone can follow, but limits posts to one a day. In addition, access to public accounts is not possible on cellphones, making it more difficult, for instance, to launch an incriminating photo of a public official into the blogosphere. Comments are also deleted after a few days, making long-term discussions challenging and erasing a historical record." Is this the natural result of government meddling in online conversations? What will chat services in China (and other speech-stifling nations) look like in another five or ten years?
