We wanted to make it simple for other participants to share answers. As soon as AnswerPoint was deployed, we saw that so much of the user experience is determined by the presentation modality. And there's a temporal element of information. If a question doesn't get answered in 3 days, the chances of it getting answered decreases exponentially. It gets lost.
Usability studies show that.
We want to resurface the older questions. One reason questions don't get answered is because the people who looked at it thought it was superficial or not worthy of an answer. The moderator can raise worthwhile questions again. Also, they can watch for people using excessive profanity. And, the moderator can re-categorize a question if the person asking it put it in the wrong bin.
