>> "Avoid asking users for their title. It’s extra work for them and you’re asking them to potentially reveal their gender and marital status, which they may not want to do." I'm always a bit surprised when I see some e.g. tech conferences still insisting on title as a mandatory field (or really asking at all). It's not just the gender and the marital status but some people attach a lot of significance to all manner…
At least in Germany, titles are still rather important. I agree that it's silly but if you have a PhD you're very likely to put "Dr." on your doorbell name plate.
[1] Well, personally I think that's silly too. But it's a question of degree.
