It was a quick way to evoke feedback from the group as an exit ticket activity.

I used this as a quick way to collect anonymous feedback from a group who visited the library as part of a workshop. Students were able to provide quick feedback. However, due to anonymous nature of the posts, I had a harder time following up with individual requests.
It was a fast way to gather feedback and students could react to comments others made. It was my first attempt to use Padlet in this manner.
I have since used it as an online bulletin boards to post photos, screen captures, anecdotes and comments.
