User Interaction Consultation/Request information
Often, people cannot find what they are looking for. So, why not ask them to leave behind what that is? If enough people request the same info, maybe that is a sign that either the information is hard to find (redirects!) or that it is in demand, and could get priority. They could get feedback about where to find it later.
Problem it solves
Give people a sense of low threshold ownership, and that they participate in the process. At the same time, point out gaps in our information system.
Would have to tackle issues around pointless suggestions etc, and unsure if the ratio would be good...
