It's not that impressive (at least not morally). It's a pretty self-serving amount, since it generates more earnings than it costs.

Undisciplined

I still have my default as 10 but I rarely use 10. Typically 50 or 100. Although 10 is useful for when you are tagged in a discussion such as this one. Then I will just zap all the notifications 10 and engage with the ones I want and zap the ones I am directly involved in either 50 or 100. 

tbh, my zap default is 1. I just like to be precise.

288 was pretty damn impressive until now.
