The greatest joy of LiveJournal, and other similar proto-social networks and chat rooms, was their uselessness. There was no reason for any of us to be there, not really. Online sociality may have addressed loneliness, but in its early form, it did as much to simultaneously heighten it, isolating those of us who sought out artificial social lives in two-dimensional typefaces.

It's an interactive and immersive CV, an archive. It all counts, and it all matters.
