In case you missed it, Waxy has a fascinating story of the lost Hitchiker's Guide to the Galaxy sequel computer game.
Plus, Neil Gaiman just posted the introduction he wrote for an Adams biography:
I think that perhaps what Douglas was was probably something we don’t even have a word for yet. A Futurologist, or an Explainer, or something. That one day they’ll realise that the most important job out there is for someone who can explain the world to itself in ways that the world won’t forget. Who can dramatise the plight of endangered species as easily (or at least, as astonishingly well, for nothing Douglas did was ever exactly easy) as he can explain to an analog race what it means to find yourself going digital. Someone whose dreams and ideas, practical or impractical, are always the size of a planet, and who is going to keep going forward, and taking the rest of us with him.
