"Felix Baumgartner is a boss," tweeted Jozy Altidore, a soccer player for the U.S. men's national team.
Two threads related to the jump made the front page of Reddit. Users quickly upvoted a request for Baumgartner to participate in an "Ask Me Anything" on the site, where users pepper someone on the site with questions about anything they want. President Barack Obama held court as the subject of a similar thread in August.
Nearly 29,000 users weighed in on a separate thread about the jump itself, voting it up and down and robustly commenting.
