Marc Canter

Founder of the company that became Macromedia, Canter has also served as CEO of Broadband Mechanics, which produced People Aggregator, a social networking tool with source available (but not under an open source license).

His blog, Marc's Voice, frequently critiqued other Internet luminaries and competitors, such as Mark Zuckerberg. Known for his boisterous appearances at technology conferences, Canter made no secret of his left-leaning politics, identifying himself as a "red diaper baby" (i.e. politically left-wing since infancy) at the 2005 Gnomedex meeting in Seattle.
