Saying that he was initially excited to attend South by Southwest, Arm & Hammer representative John Meyers told reporters Tuesday that hes now uncertain how exactly the leading manufacturer of baking soda fits into the music, film, and interactive festival. My boss gave me some explanation about why I was goingsomething about giving people an interactive household products experienceand it kind of made sense at the time, but now Im a little confused, said Meyers, 44, who spent the entire day Monday at the Arm & Hammer station handing out free baking soda and toothpaste. I mean, we have a Facebook and Twitter account, but our web presence is pretty muted compared to what most of these people are talking about. Folks seem to appreciate the free deodorant, though. At press time, Meyers was remaining mostly silent while seated on a panel entitled Hardware Hacking: From DIY to Revenue.
