This is awesome, I love it.
However, is anyone else concerned that the driver seat of HN is essentially being handed over to new users as more advanced users switch to services like this or "HN daily" or even the "/best" page? It seems like the people that don't know anything exists beyond the front page will become the only ones left to do the work of curating content.
(just speculating, nothing against new users I haven't been here that long myself...)
