It is my experience as a developer of a text editor, that text edtor/IDE users make the decision whether to learn/use an editor within seconds. Just a quick look and it has been decided, in 3 seconds what they will spend their next 10000 hours working with. I do not understand this, but it is a phenomena. It's like when we look at the opposite sex and decides if he/she might become our future partner and live the rest of our life together - and the decision is made within seconds. At least the filtering-out.
