Writing is harder than talking. In my experience, people who don’t care spending time writing properly, well, they usually don’t care about your time. Or perhaps it’s just me, since I’m a non-native English speaker, at work I re-read (and rewrite) what I write many times before hitting Send. More often than not, it’s in the rewriting of my own words where I find the solution to the problem I was about to ask (duck rubbing or something like that they call it)
