We had a nice seminar yesterday from David Parker (as previously noted here). It was a discussion of some of the difficulties involved in editing the NT and some of the opportunities provided by digital presentation of material. I didn't take detailed notes (it wasn't that sort of talk), but I promised Tommy a picture instead.
Among the many interesting issues raised were: 'which came first, the text or the manuscript?', 'to what extent has NT studies worked with a modern concept of authorship projected back onto the past?', 'what is the impact of the fact that the ways in which the authors imagined their work quickly disappeared in the face of new innovations?', 'where can we place the distinction between authorial stage and transmission history, for example, for the fourth gospel?', 'to what extent do digital editions imitate and illustrate the textual fluidity of the tradition?'
David wasn't really trying to answer these questions, more just help people realise that they are questions.
Two best tips: a) look at Tischendorf, not just NA27; b) have a look at Wasserman on Jude to see what you get from a complete collation of all the available evidence for a NT book.
