how far did you get into it? the last 100 pages really aren't that worthwhile, the speech by John Galt is though...
the middle is pretty important though because that's when the economy starts to collapse. its pretty interesting, and if you like the pro-socialist bastards then I would recommend reading the whole thing really. They start to really fuck things up in the middle of the book.
you should read the fountain head :O that book is awesome. although the main character is again faultless ;]
