I've participated in all 3 of the "Things" offerings over the years. I think they are great learning experiences and they help to keep me updated with tools/resources that I can use related to work or personal life.
An extra benefit is their cost-- free! Who doesn't like free-99? Especially with tightly squeezed budgets.

A B-I-G thank you to the MN multitype library systems for providing these opportunities! I'll be waiting and watching for the next Things to come!
