I personally think if you're given four months instead of four weeks on a play, with the people who want to work that way, the play will invariably be different and stronger, and much more fulfilling and richer on all counts. There's no doubt in my mind about it.
As a writer and sometime activist who needs to promote my books and articles and occasionally rally people to one cause or another, I found Facebook fast and convenient. Though I never really used it to socialize, I figured it was OK to let other people do that, and I benefited from their behavior.
