When I initially heard about Twitter, I thought it sounded crazy and way too mega-ego and, hello, why would I care that you just got a haircut? Now that I have been using it, oh, every day, for the past 6 months, I guess I have to admit that I find it is kind of useful and appealing. I finally put it together what is so appealing about it. Twitter is a persistent chat room. It is Babble!

Babble is similar to a multi-channel textual chat system except that its conversation persists over sessions, allowing both synchronous and asynchronous talk. Its aim is to support everyday, opportunistic interaction among members of a workgroup. [link]

I never used Babble (it was built in 1997 and used internally at IBM before I joined), but it is one of the projects that inspired my thesis research. Its key concept is social translucence:

Social translucence is the idea that we should make some (but not all) cues about the presence and activity of users of digital systems available to one another. [link]

Twitter fits this criteria and has a lot of the same features as Babble:

  • you can communicate either synchronously or asynchronously (txt, mobile, browser, etc… )
  • you can see who is present (Twitter’s following and followers pictures)
  • you can see who is active (Twitter’s time-sorted list of who said what)
  • you can selectively determine who sees your posts (direct messages, @ messages, broadcast)

The main differences between Twitter and Babble are:

  • Babble has a graphical visualization showing who is currently engaged in the conversation
  • Twitter’s “groups” are not bounded. Even though you and I might be following each other, my group is probably different than your group. It is possible there could be 0% overlap, but we could still communicate.
  • The cultural norms of Twitter are pretty distinctive in that people use “tweets” to give casual updates on their latest thoughts, ideas, opinions and experiences. The updates are not solely focused on workgroup interaction, like Babble was conceptualized to be for. But I see this as Twitter’s unusual strength.

It would be great if Twitter had some social visualization capability. (Maybe it does? Anyone know?) Then it really would be Babble, adapted for the flexible, ad-hoc type of collaboration and communication we do in this post-2000 world.

If you haven’t read them already, I highly recommend these papers on Babble and social translucence:
