I agree that Idoru wasn't that good.
Certain portions were okay like the idea of a Quantist watching over particular Simstim celeb's but the sotry wasn't his most imaginative.
I know that when the book was published the website that accompanied it sat their with nothing on it. Perhaps he knew it wasn't his best, but people shouldn't get too disheartened.
I suppose it's a bit like how people see the newer Star wars, as once upon atime those films were cutting edge and the only film to be made that year, and now adays people are use to those sorts of films being pumped out within a few months.
So perhaps the world is just catching up with Gibsons prophetisisms, so what imaginative streaks he might write, become tainted at what we see nowadays.
I did wonder about a few things, for instance their has been rumours for the past Two years of a Neuromancer film, of course I haven't seen anything materialise, most information points at the rescripting not being to Gibson's liking but I have no proof of that.
Of course I would prefer to think that he's waiting for the correct media, or special effects or idea. I looked at two possibilities...
1) Neuromancer is created like Final Fantasy was, That would capture my imagination and I'm sure it would others too.
2) A Neuromancer is created into a Series first, I thought of this one, it could work, building up some following, afterall some people tire of Star Trek and others have never read a Gibson book. Perhaps that's the answer.
As for other books, Well I do have a few of Bruce Sterlings, I read one or two of the short stories from "Global Head", to tell you the truth I've built up an expansive collection of Gibson and Sterling but haven't even started to read them yet. (I think I should get some glasses or something first hehe)
I will keep an eye out for books by the people you have mentioned, Knowing me I'll probably buy as many as I find and stock... I'll go blind before I read them all.
I did once find a Audio version of Neuromancer read by Gibson, admittedly on the net. That's a good way of hearing it, straight from the author, you can then tell how he wanted his characters portrayed.
I found this Gibson site once that I liked
http://www.8op.com/gibson/en/, I got hooked into playing the DOS Neuromancer Game. (Which is based on a mixture of Burning Chrome/Johnny Mneumonic/Neuromancer)
