Actually the topic on a PDF version of the Guardian had not got lost. It was moved from 'BBC' to 'Press and Publishing'.
Very sensible too. I started it in BBC not realising how many sections there are. I thought it was all media. So some comment will be there not in this blog.
Other contributions have started to look at the Times as well as the Telegraph. There will be a log of reader experience. I still think the Guardian should say something about what they intend. July is a while ago now. And surely other media could report on this? The Telegraph is not promoting the Active Paper option all that widely as far as I know.
