I love 'free wheeling.' I use book forums a lot and love picking up recommendations. This is a new thing for me, since Borders closed down I no longer have a good local book store to browse covers and blurbs. Instead I have an eReader and love discussing books and have widened my range of favourite authors greatly.
I was tempted to take the next step and partake in reading challenges - but decided this is a step too far - will continue to impulse buy on recommendation.
