Another facet of the ConfChem model is the “list.” Although ConfChem evolved out of listserv discussions in the early 90s, there are advantages to continuing the use of this mode for social communication, although it does not need to exclude other forms of social media. Email is the most ubiquitous form of internet communication and almost everyone has an email address, while many do not participate in other forms of social media. It also needs to be understood that people do not reply to emails, but comment on a paper, which in turn triggers an email to the list. This is important because people often use email for personal correspondence and are writing in a less-professional mindset. When you comment on a ConfChem paper you are physically submitting your comment to the site of a professional society (the ACS Division of Chemical Education’s CCCE), and are clearly aware that your comment is being posted to a publicly accessible scientific paper. The result is that the comments become valuable features of the paper. For example, purveying a few papers from the Spring 2012 ConfChem reveals the following: Paper 1, “An Introduction to the International Year of Chemistry-2011” (all papers are accessible from reference 3), is two pages in length, but has six pages of comments, including links to multiple resources. Paper 6, “The Periodic Table of Isotopes for the Educational Community,” is 9 pages long and contains 25 pages of comments.
