Since I live in Canada, I have to be aware that there are laws limiting speech in very specific ways, and that their effect is to 'damp' speech around those subjects in a lot of vague ways.

A similar thing happens in groups of people. One-on-one, people might explore dangerous, even offensive ideas. Add more people, and very soon, the only thing everyone can agree to talk about is that everyone agree.

Agreed?

Anyway, it kind of homogenizes twitter, facebook and most other platforms.

I wish 1a would mate with 2a and the result be a discussion tool (with optional protected anonymity) guaranteed to every citizen.

But I probably wouldn't like what I found written there :)
