Ask HN: What do you want to be notified about?

Hi.

I'm developing some sort of "any kind of alerts" app. You can think of it like it is ifttt but just with the IFT part: something happens then get notified.

I'd love to know what kind of alerts would you be more interested. Can you help me? I will try to add your notification ideas to the app.

Thx in advance!

ps. I have already included classic alerts: weather, sports, tv shows, mentions, concerts, website-down… but for sure there is a lot of geeky stuff I'm missing.
