Currently working on HN Alerts — a simple free site I made to alert me (via email) to trending stories on Hacker News.

It sends me an email once a story hits a certain number of upvotes per minute, so it's useful for keeping track of breaking news.

It'll also soon allow you to get alerted to specific words or phrases in titles. (I have one set up so the monthly hiring threads notify me as soon as they appear.)

So do you get one email per-story that fits this criteria? Or is it some kind of roll-up?

Typically one email per story.

It checks every 5 minutes, and if more than one story happens to meet the criteria during that 5 minute bucket then it'll put them into one email (so the "hiring" checks appear in one email). But in reality because it's rare that 2 stories will trend within the same 5 minute bucket it ends up being one email per story.
