With the exception of the millions of people in the world that are oblivious to crypto, I do believe you are on to something... I have already seen some very enterprising Steemians run crowdfunding projects on this platform.

Currently, my biggest issue with crowdfunding is, as you stated, marketing. I do not see the purpose of having to spend large amounts of money to raise money in this case. You may as well use the 'marketing' money to make money in other ways...

Crowdfunding does need an overhaul. I will follow you, so let us know what develops...
