Hacker News Reader

I agree, that is a poor choice to have as the only way to share something. An easy fix would be to add a link on each item as a kind of synonym for the Share button in the G+ bar. That said, the problem is a pretty minor one given the extent of the redesign. I'm rather happy with the new Reader myself.

And it can't be done with the keyboard. I used to use 'l' to like and 'S' to share. Both shortcuts are gone.

try perhaps sendto?
