Thanks for posting this thread!
I have been reading other posts from those who are so involved in their Reading Life, chasing certain rewards and complaining that there aren't more rewards to earn and I was starting to wonder what was wrong with me.
I have Reading Life turned off.
I was initially mildly interested in keeping a record of my reading ie how long in total, how many minutes per session, how many books etc. However due to the storage error issue from last year and problems with the 1.9.16 update I have had to reset my Kobo almost as many times as I have turned it off. I sideload all my books and so I never sync. The statistics that I do accumulate are so inaccurate they are meaningless.
