The last few weeks have seen a tremendous increase in interest about ePub. Many new blog posts have been written trying to explain the format. We’ve also seen a big jump in the number of publishers coming to Threepress for help with tricky ePub problems or just asking for guidance about the format. While I’d like to pretend that the growth is due, in part, to a long-anticipated awareness about the benefits of open standards among consumers, publishers, and suppliers, I think it’s more likely that it was Steve Jobs’ explicit mention of ePub support in iBooks on the iPad that drove most of the excitement. What makes me most excited about this groundswell is the sudden interest in ePub from a number of clever developers.
