In my ongoing research I've used about every tool I could find to connect things.
-markdown/pastebins
-evernote
-wikis
And I think something missing is a visualization of the connections (like pic related but less conspiracy focused)
And the biggest problem with a Wiki is that all the articles are under a single namespace (the whole universe). I'm thinking of something for shorter timespans, with far more focus. Like who is connected to XYZ org? Drop XYZ org in the middle, start making connections that can store facts (websites, archive links, images, docs etc...) OCR images, index text etc...
The idea isn't to have a Wiki of everything known, it's to keep track of research and continually see the forest for the trees. Maybe the links between items have contextual scores or categories.
For example: Amazon has a link to Bezos, the link type is ownership relates, employment related, financially related. Bezon has another link to WaPo that is financial, ownership related, but not employment related. The user could strengthen links by providing more docs, archives, etc... (proof). The user could also visualize all of these relationships, or maybe just show financial relationships etc...
I'm sure something like this exists, if it doesn't let's make it. If it does, but sucks, let's make it. If it does and rules, tell me to STFU and link me.
The blockchain thing was mainly a joke, but since every ICO is a fucking scam, why not get popularity going by having something like MuckCoin or FactCoin and pay people to validate facts on the links. Store links and facts on a blockchain. Anyhow fight me.
