I have been spending more time reading questions and answers rather than trying to gain rep points (which I am not really good at...).
One thing I have been doing recently is looking at highly reputable users and checking out their favorite questions. It gives me a good insight into different technical areas, that I wouldn't normally stumble across.
What would be really good is that from a list fav users I have selected, I get updates when those users add new fav questions.
I think this feature would give a SO user more richer content in terms of learning and understanding questions posed and answered on SO.
