I think that what we need is more visibility of the forum to the surface of the Internet, it's not enough that we're at the top search when searching for "Bitcoin Forum", we need to put in some ads on other websites, I think that's what we lack here but I'm not trying to say that's the only solution, maybe there are some and maybe this solution that I'm getting isn't even good with the staff and administrator.
Bitcoin forum is a non-commercial one and it has no need to advertise any where. Advertisement nowadays is very costly and even Bitcoin forum has budget for operations, paying staffs for their moderation jobs, it does not mean the forum need to pick pocket money for advertisement on the Internet.
With very different structure than social media, what do you expect that advertisement will help Bitcoin forum gain massive exposure and new users?
Incompatibility between Bitcoin forum and other social media platforms is big minus for any
paid advertisement program.
