I'm curious about the organizational aspect of your project. that's a nut I've yet to crack. what was your strategy in building a community around your project?

First, we want to make this tool really usable to the individual and gather a couple of thousand users with it.

Without the needs of an individual fulfilled, there won't form a "fact-checking" community after all.

We want to spread it by engaging in those groups on the web where fact-based discussions are happening, as well as the general science communication community. Also providing/gathering more tools and useful content that help our users to do their work more efficiently. Basically by building a content brand around collaborative web-research, fact-checking etc.

Then in further development, we make the sharing part possible, from which we think that a community will form quite organically.
