First of all, I'd like to apologize for being so busy lately.
Anyway, with the recent talk about this Wiki and all that:
I always pictured Helixpedia as a place to preserve TPP. The GDocs are good on solid facts, but they don't contain anything more than nicknames outside of that.
At the same time, you can find a decent amount of facts and a whole lot of opinions on Reddit, but it's hard to sort through 6+ months of posts.
Helixpedia, at least in my mind, would make facts easy and efficient to see and at the same time would give solid insight upon the crowdsourced lore of TPP. Thus, facts can be hyper-specific (as long as they aren't irrelevant or redundant) but any hype and lore should be kept broad.
As a general rule, if it's "some people" or "a few people" believed something, it probably shouldn't go on a page. The exception to that is if whatever it was made an enormous impact on the stream or TPP in genera.
Helixpedia was also meant to provide a source of information for other, miscellaneous events, like TPP3DS's Ocarina bit and stuff like that.
My two cents, anyway.
