I would like to thank you for creating go read and making it open source, it's what I use as RSS reader, using my own free quota of App Engine. I hope I can contribute back some day.

  "30-day trial: This action cost me about 90% of my users. Many were angry and cursed at me on twitter. I agree that it is sad I did not say I was going to charge from the beginning, but I didn't know that I would be paying hundreds of dollars per month either."

Honestly I think the sense of entitlement nowadays is way too high, people use a product that is free and needed weeks or months of your own free time, and then complain about it when you change it.

If you decide to charge for it, you're a greedy bastard, instead if it's free, they say "if you aren't paying, you are the product". Other complain that the product doesn't work, when instead it's a case of PEBCAK. When it's not, it means you're going to say goodbye to a couple of night's sleep or a weekend or too, or maybe it's ONE feature away from being perfect (again).

...sometimes I hate people :(
