Famed literary critic Lionel Trilling once described Henry James as a "social twitterer." Sure, he meant it as an insult, but it makes us feel better about having signed on to become twitterers ourselves. We recenly debuted our official UnBeige Twitter account—your source for terse and downright laconic breaking newsbites, event snippets, and links of interest. Why, mere minutes ago we wrote of Puma's plan to collaborate with Sergio Rossi on sneaker-inspired pumps (see above). Meanwhile, the mediabistro.com tech team has worked its magic to add to the sidebar at right a handful of our most recent word bursts (limited to 140 characters). Sign up to follow all of our twittering, and start twittering yourself at twitter.com.
