On Friday, the John F. Kennedy Presidential Library and Museum will continue its @JFK_1963 Twitter feed, which sends updates from the life of the former president. Organizers say, however, that the tweets, drawn from news accounts, will not include any "erroneous reports that later need to be corrected, or, for that matter, raw, emotional outbursts," the New York Times reports.

In other words, not like a real Twitter feed at all.

And too bad, since as these key 5 minutes of Walter Cronkite and company show, the actual coverage sometimes had a Twitter-like feel, with staccato bursts of news and background, rumor and confirmation — and for all of Cronkite's restraint, one of the most famous raw, emotional outbursts on record.
