When my Google news alert ticker started spitting out reports of a bill to block access to Myspace, I put my eyes back in my head and thought: man is it ever hard to write about a moving target.
During the three or four months I spent working on an article about Facebook (which is now out and off and gone and done—for now), the site changed in about a dozen ways, as many students were expelled around the country because of their postings on Facebook, and facebook.com expanded to include corporate employees. Moving target.
Moving targets make writing like way, way difficult for the obvious reason that (for the sake of accuracy and "remaining current") you're always having to add, delete, and revise what you've just written. But the other thing that makes Moving Target Composition vertiginous is knowing that there is no way, when I think I'm done, I will really be done.
This is in part why, at the moment, I'm thoroughly enjoying starting to work on a chapter about the visual rhetoric of taxonomic discourse in the 19th century. The target, it does not move.
Look! There it is just waiting to be made sense of.
