Ideally we should build a new one with the same overarching goals, on Steem or similar, and not try to salvage the existing Wikipedia.

Wikipedia allows commercial [reuse of their text content](https://en.wikipedia.org/wiki/Wikipedia:Reusing_Wikipedia_content), with attribution but without suggesting their endorsement (i.e. don't use an account name like @wikipedia for this), so anyone could start posting wiki articles here. And the proceeds would hopefully be donated back to Wikipedia. *Edit: This would be bad for Steemit.com, because Google penalizes duplicate content in search result rankings.*

Hosting all of Wikimedia's content on the blockchain, including images, would probably require a dedicated blockchain. Would that really be cheaper than a centralized website? I don't know.

As for @gavvet's post, I don't think paying contributors is what they need. Let's not try to improve a system that works remarkably well by changing the basic principles.

Check this out from a few weeks back:

Let's hope so.

A text-content blockchain is an excellent platform, pretty much perfect, for a highly censorship-resistant wiki. It will take someone's will to build it, and it may require changes to Steem to make incentivizing good edits possible.

Yes, the steem blockchain can solve the problem of content and data monetization of the entire Internet!
