While I was going through the twitter round up, I couldn’t help but notice that the semantics used to address other tweeps include the @ symbol. That got me thinking about how the @ symbol shows up not only on some web services, but also email, blog comments, and even in the Getting Things Done methodology. I also recalled someone saying that the German name translated to “monkey tail” instead of the widely used “commercial at.” After some research, I discovered where the ubiquitous nature of the @ symbol symbol fits and where it potentially could grow.
