If we only talk about "creating jobs", we'll never really get what we want
It's a lot more popular to talk about jobs than about capital...but wealth is necessary to buy the tools that make labor productive. Ignoring that necessity is a bad way to run a country.
Nobody really multi-tasks
We can suspend our attention to one matter and give it to another, and even cycle quickly among those things, but we can't really do two thinking things at once. Tragically, that was illustrated by a helicopter crash caused by the pilot's inattention to detail during the pre-flight inspection. He was distracted by text messaging.
Bad ideas go viral
A public-health study found that people are quick to believe nonsense (about the flu vaccine, in the case of the study) but not useful information. That suggests we need to think long and hard about how to disseminate public-health messages; apparently, it's a serious uphill battle. A lot more thought needs to go into how to make useful thoughts go viral.
Domain names are cheap...don't overlook them
If the Obama campaign machine (which is morphing itself during his second term into a perpetual-campaign machine), despite its much-vaunted online organizational skills, isn't sharp enough to have registered their new name as a domain name before rebranding...well, then just about anyone could probably use the reminder to protect important names as assets early on. Register your own name as a domain; do the same for your children. On a related note, none of us should be surprised at all when the "Obama For America/Organizing For Action" team decides to try to put First Lady Michelle Obama's name into contention for some kind of high office. (Strangely, though, nobody on the campaign's team apparently ever thought to register MichelleObama.com. They'll come to regret that.)
