The official Foursquare account just sent out a tweet letting everyone know that today is already the service’s biggest day ever. This is interesting since it’s actually the day before the SXSW conference kicks off in Austin, Texas. According to the tweet, Foursquare broke 275,000 check-ins (the previous record, set last Friday) for the day “hours ago.” This means they’re very likely well past 300,000 now and perhaps even higher
