Before twitter created user lists, I hand selected scientists and science types on Twitter to help you find new and interesting people to follow.
I started the project with 100 of my own Twitter friends back in January 2009 and expanded the list to well over 600 members by November 2009.
I migrated the old manual list to Tweepml.org and then Twitter announced the release of its own lists system. I then added my scientwists to a twitter list.
Creating such a list doesn’t seem to have as many advantages as the Tweepml system, but it is worth doing nevertheless. It does. however, offer users a way to share their “filtered” lists with others. So, view that stream for tweets only from science types.
Unfortunately, Twitter lists have a limit of 500 members per list. You can create 20 lists per account. I have created several additional lists in various science categories including physics, bio, chem, and sci-comms.
Twitter lists offer yet another metric for those who worry about such things to focus on. Last time I checked, I was listed by other twitter users 620 times. On how many lists are you listed?
