Yes on all counts. I wouldn't want our Demo Day presentation disseminated because it kinda sucked. And I wouldn't do it again, because when I next present I expect a big fat check to follow within a month or so. But maybe I'm just lazy.

How can there not be any value in this? If not for the practice at least for the fanatical viewing this particular audience will do. And I'm also surprised at how little the companies communicate their product idea or vision. But maybe I'm focusing on the wrong thing.

I tend to agree. People may be underestimating the benefit that the increased awareness would give. Serendipity is powerful because "random" people often know the "right" people.
