CCP has an economist that watches EVE's economy. They even put out quarterly newsletters that in game investors watch closely. With Valve doing this as well soon virtual economist will become a real job.
That is not what is going on here. Youtube accounts used to be separate from Google accounts but you could link your Google account to Youtube. I am betting a lot of people do this because it means just one login or all Google services. Now Youtube accounts are being slowly migrated into full Google accounts, no more special Youtube accounts. At some point in the future it will just be one single sign on for all Google services including Youtube.
How is this bad? I don't think it is at all.
What people seem to be getting confused about is Google re-branding and integrate the social features that already exist in their products into one service that exists across all products and the new account is called Google+.
Youtube has likes/dislikes, comments, subscribing, and messaging.
Reader has subscribing and recommending.
Picasa has friending, subscribing, and messaging.
Docs has sharing and collaborative editing.
Latitude has check ins and friending.
Google Profiles had a bit of everything.
The new G+ account replaces the old Google account even if you don't make a profile, and you don't have to, so that all it is is a name change.
To sum up:
Youtube accounts are becoming full Google accounts that are now called G+ accounts.
Talking about geek video and no mention of TWiT.tv? They do twenty-eight live shows that amount to some forty hours of live streaming content a week. Not only do they cover a huge base of topics but they are profitable and just moved into a big new studio.
Where do you get tech news, NY Times or The Verge? Sure some big tech news sites are owned by media conglomerates but that is mostly from acquisition and there are plenty of blogs that aren't selling out.
If you look at broadcast/TV/live news coverage of the tech sector which is better, CNN and G4 or TWiT.tv and Revision3?
It is only a matter of time until some one gets as successful as TWiT.tv doing comedy or drama or regular news. That is when the existing media companies will start to really feel it, when solid, high production value but extremely cheap to produce content stops being something that they can pass off as "interesting only to nerds."
