So this is based on the discussion we had at ScaleSummit. There, they said you should respond within 24 hours (see my notes under "Respond quickly to external contributions" [here](http://www.annashipman.co.uk/jfdi/running-oss-projects.html)). 

I want us to manage expectations here because I want people to know that if they submit an issue or PR at 10pm on Friday night, no-one is going to comment on it until Monday because this is a project we work on in working hours. Hence the "working days", and two days to give us a bit more time :)

By comment I mean it could be “Thanks for this, I am going to review it in a couple of days”, I don't mean review or anything else - just acknowledge. Shall I change "comment" to "acknowledge" or something else?

I don't think that someone acknowledging a PR in two days is something we can't or shouldn't commit to, but @carlmassa might have thoughts...
