Video Series (Day 51) It was the day after Christmas and we invented the Air Hashtag, its almost 2012 and it is about time to ditch the air quotes and go air hastag on yo asses! Meg and I visit the pub and run into the guy from dominos. Its air hashtag time, if you are on twitter and need to explain a hashtag to someone in a conversation, don’t be afraid to use the air hashtag. Its a simple way to air hashtag your comments so you can converse twitter style.
