I think it is an interesting idea, but would work better
in theory than practice. Here are my main concerns:
- I am more likely to take out energy to answer a more
obscure question if others have not answered it. With
this system I would tend to assume that it was answered
and wouldn't answer. I suspect others would do likewise.
- Conversely if the question is basic, there are a lot
of people who will want to take the chance to answer one
that they can get, and the hapless questioner would get
a flood of answers from people who could not see others.
- I think that some of the most valuable answers given
come as feedback, improvements, and corrections on
answers others gave. This would remove opportunities
for that.
- For very short questions it is already fine to use
/tell in the chatterbox, edit your home node, etc.
People already do this.
