Yes, I admit, the vote came first and now I have read it. That is typically for most post that I read. I am late late to read post, firstly because of my time zone (I am always behind) and second because of my stage of life (I am always behind!).
With the introduction out of the way, I think the general idea is great to find out more about the fellow hivers from the metadata of their interests. Even today I had a strange conversation where I know two individuals well (maybe one more than the other) but as I tried to mitigate they got more drifted. I thought it started with a simple misunderstanding. Maybe your tool can help us with situations like this.
I am unclear about the method from this short post. Is it possible to elaborate on a future post.
I think you should be able to write a DHF proposal for this and it can get funded.
Cheers!
