I would not use Facebook if they did all that and paid me $5 per month to use it. Or even $50 per month.

The site is spyware incarnate, and it'll take a lot more than a TOS (not even a piece of paper) and an "Independent Board of Facebook Policy-makers" to make me trust the site enough to use it.

It would have to be totally revamped technologically to be fully anonymous -- and peer to peer, so that the only people who get my data in the first place are my friends. Not some corporation (no matter what promises it gives), but just my friends, and only my friends.

Even considering their number of active users is bunk, there's no way they've reach anything close to $100/user/year - that would mean they only had 42M users.

2) I don't think the suggestion was for them to shift to another revenue model, I think it was to give the option of subscribing. Much like many other sites e.g. Slashdot, Reddit, etc. Most people would probably still choose the free option.

2) they can't offer such an option, facebook is a machine designed to collect, store, hold and aggregate user data and they built a business model out of it. Putting the user in control of its data is the opposite of what facebook wants. You can't really compare the subscription of news aggregator websites and an hypothetical subscription on facebook. Facebook is unique in the fact that it holds user personal data and has a strong grasp on it through heavy vendor lock-in, you can easily leave slashdot or reddit and get your news elsewhere from an alternative but you can't leave facebook easily because they have your data, data you need in your daily use and there's nowhere to go to to find an equivalent.

I guess I could send that to a school or hospital or some such. But it'd be neat if they realised that some people are happy to pay for good reporting.

Maybe there's a need for some simple online-only sub, with feedback buttons of "good quality" or "poor quality" on each article.

That's what you're missing.
