There actually is an ongoing experiment that does this and is even supported by some witnesses and people who have large stakes on the platform. The experiment is called BurnPost and I highly suggest you check it out here: https://steemit.com/@burnpost 

As a small minnow, I for one will probably not participate yet on such campaigns. While I do understand that the simple act of Burning Steem if done in large quantities will make the price of Steem increase mainly due to the Law of Supply and Demand, I don't really think atm my measly $0.01 upvote or my little liquid Steem atm would matter much. I'd probably wait until I get enough support through upvotes on my daily blog posts before I consider helping the community with such campaigns.
