There is an adage that says "feed what feeds you". Promoters indirectly feed us by bringing in investors and wonderful content creators who help propel Steem forward in a much more hastened manner. Currently, Steem's price is skyrocketing and promoters are indirectly influencing it in an appreciable way. Hence, if we can contribute to their growth through Upvotes, Resteems, etc then so be it. Also, delegating to the Promoters community can also be one of the best case scenarios. I have plans to delegate to this community and few others when I obtain significant SP. Hopefully, by December it will be a reality.
