Instagram solved the problem of sterile looking mobile photos. Most people taking mobile photos are amateurs, and can use any help they can get to make their photos look better. That's why instagram succeeds. There's a lot of people who want their mobile photos to magically look better (or at least look more like instagram style photos).
Ustream and Qik have made live video sharing easy. The fact that most people aren't familiar with either is because there isn't much demand for live video broadcasting. I don't see push vs pull as being any kind of differentiator here. It was already trivial to ask someone to live broadcast an event (text messaging is ubiquitous) or to watch one in progress.
