You bring up an interesting point here--there is reading and there is reading. Judging from your number of posts, you've done quite a bit of reading about poker, right here at CC.

The format is different, is all, because the wealth of information in the forum could comprise more than several books.
Then there are people who just plain aren't into reading at all, including joining a forum for that very reason--my guy Mike is one. He learns by playing and discussing the game. Everyone thinks that's ironic, btw, because I am the total opposite.
Moving right along, I agree that some day a book will come out purported to be "by Phil Ivey". Will he actually do the writing? My money would be on a ghostwriter or a "co-author".
