Well yes, I know that he actually died in 1950, but the clever folks who set up the Orwell Prize for political writing seem to have brought him back to life again by publishing his diaries online, at the rate of one blog post a day.
According to the BBC Tadio 4 website (where you can find podcasts of Orwell's son Richard Blair reading extracts) :
But Orwell wrote about other issues beside politics :
... (he) was also interested in travel, food - and even slugs. ... he even includes newspaper clippings of sloe gin recipes.Another famous dead author blog you might enjoy is that of the famous C17th diarist, Samuel Pepys, which I think is great enhanced by the use of hyperlinks to explain all the references. (This is, I think an example of digital literature working far better than the print version.)
These diaries seem to suit the medium so well that I have no doubts that if these guys were around today, both would have been happily blogging away!
