Any good ways to capture initial “WTF”s of newcomers?

any new comer going to a new place/company/group/... will have initial questions/surprises/feelings/opinions/... - good-or-bad.. Some time voiced aloud. i believe these intial WTFs have immense value (and sincerity) - for both sides to learn about themselves.. But their amount and content quickly decline in time, as the individual is changing/adapting (or being shaped) into the new form. So, how best to capture them?
