Incentive or not, I know that some of the members here really couldn't care less.
This was never about money. People who didn't share the sentiment aren't here anymore. Thing is bro, all of this will be here. People will come and go, but this wont. That I can promise. No matter who ever says what.
They are long gone, thing is, nothing is or was promised. From the start to the end, this was all about contribution; giving back to the chain and the community. Those who understood that part never looked for any incentive and are still here, showing up when called upon.
Right now there is some absence, a fair bit of inactivity too, but when they are needed, most of the authors always show up.
