The venerable Wall Street Journal has given up trying to age gracefully after being purchased by News Corp., and today the bandages will come off on a facelift that took six months to complete . The main difference will be that non-subscribers will get a more general-interest homepage full of links to free lifestyle content, while subscribers will have the page tailored to emphasize business news.

So bring on the social network!Meanwhile, just as the Journal is trying to expand its readership beyond managers and executives with expense accounts, Slate is introducing The Big Money — billed by the New York Times as "a Business Site for the Facebook Set ," which includes a Journal-watching Twitter feed . Because as we all know, the Facebook set doesn't like to read anything over 140 characters.
