Apropos my recent post, the blog Murketing describes tweeting as play. I can't really comment because I don't use Twitter, but Rob belabors some of the same saws I do. Also, his writing feels uncannily like mine.
One point Rob makes is that Twitter users describe it as productive because that's more socially acceptable than calling it play. Remember me saying people justify DIY by saying it saves money? Yeah. We find it necessary to rationalize so many healthy things. What healthy things aren't we doing because we can't rationalize them? Things like, maybe, nothing?
