You’re probably most interested in my work at Safari Books Online.
My old employer, Threepress, developed the Threepress Blog, 
which includes a lot of articles on ebooks. Our EPUB reader, 
Ibis Reader is also part of Safari Books Online. There is also an 
older blog, here, some I’ve written or used as an example in a 
blog post, a PDF from a talk I’ve given or else some local photos 
or Flickr photos.
