Some censorship, but infinitely less than Twitter. Can't set the resolution for videos, so even short videos are huge (a 2-minute video can be 100MB), which is slow and unnecessary (plus chews through data) when using a phone. The privacy settings default to being wide open. Worst of all, the app automatically lets everyone on your contact list know you have installed the app and want to connect, including your boss, your plumber, the restaurants you have on speed-dial, your granny, etc.
