+1 I do not fathom the people who have been downvoting my comment. By all means, if you find someone on this site who submits nothing but link spam, downvote and flag them. Otherwise, why get your knickers in a knot about me getting a pittance for recommending a book I happened to like?
I have learnt to ignore HN downvotes on my comments, and am now learning to also ignore upvotes. Thinking about internet karma is not worth anyone's time, especially because it robs you of your sense of humour.
After stoping to care for downvotes and upvotes, I started to see my karma as a _wallet_, with it I could _spend_ points in irrelevant comments, bad jokes, etc., but not carelessly, just enough to have a good laugh without compromise or worry. Positive points in my _wallet_ means I'm still contributing positively to this community, just that.
