Alex is the name of many Buzz Out Loud listeners. Recently, it has become a running gag that all Buzz Out Loud listeners be called Alex (Although in the post show of 708, the Buzz team declared the "Alex" meme over). To date, a contributor named Alex has been featured on every listener co-host show (episodes 627 and 628).
