The wonderful thing about a forum such as this is that it allows people from all over the world to read other people's ideas and share information. We're all looking forward to playing Fallout 4, even those who claim otherwise, or we wouldn't even be on here. But many just enjoy reading what others have to say, which again is personal choice.
The diversity of subjects is also very inspiring, and a great deal can be gained by looking at the game from somebody else's point of view. This is why there are so many theories and ideas on here right now, and also why this trend will continue right until release.
For the record, even though I have worked incredibly hard putting my own theories together, I love reading the ideas and suggestions that other people post. And even if every single one of my own prove to be incorrect once the game is released, it will still have been a far better way to spend my time than complaining how rubbish the game will probably be. I am quite certain that the final release of Fallout 4 will prove to be one of the best and most ambitious games for many years.
