Having more kids would make it obvious how different they are from each other. Congratulations on having the courage to have more than one child!

The problem with Hellbanning (or any other invisible banning) is that there is no feedback loop from the user who was banned. That means it's hard to identify cases when moderator banned user by mistake. If there is no banned user feedback to moderator - it's hard to improve moderation skills. That problem is especially serious, when banning is done by automoderator. Bottom line: it's better be open about ban and don't hide it from anywhere.

I agree with Robert Osborne and Jasonharrop -- Google must use feedback from their users: 1) Google Toolbar data -- the more users visit certain page or subdomain -- the better. 2) Google Search results -- the more users click search results -- the better destination subdomain is. 3) Google Search results views -- the more users see results -- the worse subdomain is. Ideally, every view in search result should end up in some actual web site views (if possible). The only reasonable explanation of why Google does not efficiently do that is ... deteriorating quality of management in their search team.

"Lobby the websites you use to offer HTTPS browsing." Jeff, have you ever tried: https://stackoverflow.com/ ? It greets me with "The site's security certificate is not trusted!" and then further with Access Denied. Isn't it ironic?

I agree with Tim VanFosson and Russell Uresti -- the only reason Phil did not succeed by simple approach to A/B testing dates is that it's a movie. And movie should deliver on hopes of audience, which likes to believe in pure non-rational love. In real life (I mean in real Groundhog Day situation :-)) Phil would succeed in ~30 days or less.
