Wonderful work.
Frankly speaking, I have some similar idea the other day, what i thought then was to collect the top news.
I have the habits to read HN news everyday, mostly through my smartphone. News with more comments (>100 is hot) usually get more attentions. And I will bookmark news with more than 100 or 200 comments.
So thank you for your nice work, it will certainly make my life more easy~
