The highest number in your threshold drop-down (250 at the moment) is far too low for my taste. I'd have signed up if I could set it to 1,000.

That's great feedback! I might add a 500 and 1000 threshold too. Thanks!

Hi guys,

I made this thing because, well, I wanted it and couldn't find an existing service :-) Any feedback or questions welcome.

I currently use a website to read hacker news that provides a similar function. http://hckrnews.com will let you browse the top x% of posts from each day.
