Just got an email from former IDPF Executive Director Michel Smith saying that Bill McCoy will be his replacement. From the press release:
An experienced manager and entrepreneur, Bill most recently served as General Manager,
Digital Publishing at Adobe Systems Incorporated. Bill previously served two terms on the IDPF
Board of Directors, playing a key role in the development of the IDPF EPUB standard, and has
been actively contributing to the development of EPUB3, the forthcoming major revision to the
standard.
