If it's an ego thing that's a very silly thing to be egotistical about. For me it's always been about motivating myself to read more and noticing when I haven't made time to read. I have to make a conscious effort since it's easy to get busy with other things and stop making time.
Book clubs are definitely another good motivator, but mine meets pretty rarely right now. I like the idea of a book buddy - quicker turnaround and easier to schedule.
