Using the new Twitter list tool, I've created the ultimate twitter ephemera list.
The list includes the leading experts and aficionados of ephemera who tweet publicly.
Please note that this is a work-in-progress--I'm still adding to the list. There are a number of twitter users that merit being on it and it will take some time for me to get all of them properly listed. If, somehow, I've overlooked you, and you'd like to be added to the list, please send me a tweet (and please link to this post).
You can monitor the entire group with one click.
