Awesome post @calumam. PoB is a new token and the best way to acquire it is by adding value through content creation or curation.
Since it is already scarce in nature, burning the tokens is detrimental to the growth of the ecosystem.
Instead, we must use those precious tokens to either distribute the rewards in a decentralized way or to fund the development of the platform. IMO, doing both at the same time is a great idea.
As you mentioned, right now we should focus on the distribution. Only the main account i.e. @proofofbrainio should continue doing it every now and then. There is no need for us to contribute to that process, at least for now.
Maybe 2-3 years later down the line, when we have enough tokens in circulation, it would make much more sense for more people to join this initiative.
