I created a closed source plugin for an open source platform. I did that 4yrs full-time then got a full-time job because sales were slow & I had a son on the way. I open sourced the code, which reinvigorated interest, and paid support is ramping back up to previous levels. When I was closed source, providing support was my downfall. People would do stuff like install other plugins that conflicted with mine, and expected me to fix it. That was very time consuming. Now I give the code away, but charge for the support so I'm compensated proportionally for the time spent fixing that kind of stuff. I'm also releasing a SaaS version of the product - it's the same thing as the open source code, but obviously the users don't have to install anything or fuss around with servers, and they won't be able to break things [as easily], because they're pasting javascript into their website instead of installing server side code. I'm hoping this will be a huge market.
