I made an enigmatic reference to this on Twitter, but it’s not really something that fits into 140 characters. I used to have a little Amazon Affiliate button on the site, which gave me a small referral fee every time a reader used it to make a purchase there. It wasn’t a huge amount of money but it was more lucrative than ad revenue, which never seems to pay much of anything somehow. If nothing else, it covered the cost of keeping the site online.
At some point Amazon had a dispute with the state of Connecticut about sales tax, and in the process jettisoned all Connecticut residents in the affiliate program (so Connecticut could not make the argument that Amazon had a physical presence in the state).
Now that it looks like Amazon and Connecticut have kissed and made up, I hope the company remembers to reinstate the affiliates they dumped overboard.
