Hmmm
We could think about this but I personally don't see why we'd do that. Being active in a threadcast means that you inherently will make a lot more comments more rapidly than if you were just posting top-level threads or in the main feeds
The ease of making a lot of threads is its own way of giving you more points. See what I'm saying?
I totally understand, but Im looking at this with the glases that if you want to promote threadcasts to outsiders, we would love to have as many people posting in them as possible.
The larger they get, the easier it is to promote it.
