I think there is a cultural block for tipping at times, but can't be sure. Don't actually have data on it.
I personally would prefer streaming micropayments for everything I use on the web either by access gating or time. Just needs to be seamless for the most part. Maybe a way for creator to set a rate and then I set a rate range I am willing to pay, but if they are higher, then I have to approve if I want to view. Could also setup micropayments by site or url, etc.
Need rates that don't hurt, but with enough readers is large enough to make creators money. Seems to me incentives align nicely that way.
Could also build in a mechanism that slightly increases rates to reward creators when something is shared elsewhere many times. Build incentives into it.
This is the model we are thinking through with Kilroy.
