In case there was any doubt yesterday was a historic day, Twitter stats now confirm it.
There were 1.6 million #gaymarriage tweets. The pace peaked at 7,347 tweets per minute yesterday afternoon eastern time, just minutes after the @Barack Obama account tweeted his support for gay marriage.
The total doubled the previous record set in June last year when New York State's gay marriage law passed.
The data also shows that the number of gay marriage-related Tweets has steadily risen since Obama took office, but as a percentage of total Twitter traffic, it's been very stable for two years except for a few spikes.
