@mralanorth @blaine @shengokai And really, the divide between messaging and publishing explains more than you would realize at first.
For example: people's attitudes toward archival and full-text search. It's reasonable to have those things on your personal website, but no one wants their emails or messages being searched or archived. That we have marked them "public" is, I think, contradictory -- they are only marked this way because we want other people to see us, and it is a technical limit.
