An aspect never mentioned is that this data only fed from active users, which are the minority of people.
Majority of online users are lurkers, so all of these models are extremely biased on whom they got their information from.

I suppose if you are only vaguely familiar with Reddit you might it assume it's like a vBulletin setup where only a handful of subforums are set up by admins rather than users.
Same thing could be said of people that aren't online too much or barely never on tech forums, like John Carmack.
The thing is, there's no objectively unbiased sample of information. You could weight towards tweets or books, NYT or the Economist, arXiv or journals. The books could be bestsellers or classics. There's no right answer, just preferences.
