I feel like Amazon affiliate money is "swingy" I have affiliate links when I review or recommend books on my blog (arthur-johnston.com) I won't make any money for a few months and then I'll make $50 in a month.

The only consistent earnings I get is every summer my article "3 books developers should read when they graduate"(1) makes me some money. My assumption is there are a lot of CS grads who need the advice :)
