Of the Three Pillars of Standup (what you did yesterday[1], what you are doing today[2], what are you stuck on[3]) I really only find [3] to be of much value. Git log/Kanban board can tell you [1]/[2] if you actually need to know these things (hint: you probably don't unless you are manager/team lead/product owner).

Depends on how you're working. I prefer a collective responsibility model. I know some people prefer to have their units of work spoon-fed to them, and are willing to trust some manager that everything will fit together in the end. But especially at startups, I think things go better when everybody feels responsible for the results.
I do agree that minimizing 1 and 2 is good, but I think you can get a lot of that just by holding the meeting around a physical Kanban board and letting people point at things.
