My role on POB development as are:
To introduce more content creators to the community, most people in introduce to hive I always tell use proofofbrain.io to post any general topic, that's my own to develope and create more audience for the community.
I have also staked all my earnings since joined hive in August, because I'm new here, a friend told me that POB was worth more than hive, so I believe it will come back to what it was once worth and go high. So am staking as my own way of make POB grow.
