So I got to go to Facebook today. After this month's visit earlier to Twitter, I guess that leaves maybe, what, five or six other big campuses left to visit someday. That's not taking into account a visit a couple of weeks ago to Stanford, which isn't a big tech company, even though it does have a campus. Visiting Twitter this month, I was in a large group of people and recognizing half a dozen people I've known from work or blogging or South by Southwest and I was tweeting up a storm and having a loud, lovely, everything-is-connected time. Today was the opposite, though also just as lovely in its own unique way.
