Look at the "biographical documentaries" category on Netflix: the descriptions are mostly in the form of "[narrator name] brings you the [adjective] story of [topic]" with little or no elaboration.
They could put up a quick blurb and a trailer. I'll spend a few minutes on a trailer for virtually anything. Especially for a 'pay what you want' movie. The fact that it's about a subject I've so far had no interest in is irrelevant if it looks like a decent film.
Even if it doesn't, you can bypass the login/donation and watch the documentary before you decide how much it is worth.
Their community forum is the most popular non-Korean place for strategy discussion. I think many people get here without particularly caring about TeamLiquid itself.
teamliquidpro.com is the team proper's site
I suppose it's a bit confusing because information about this is plastered all over both the community and team sites.
As an aside, it is mildly amusing that EG, another popular US SC2 team, fronted 666 dollars.
Sure, it's a video. And it has something about Team Liquid.
