Guys: We understand that when you're in the early stages of a relationship, it's tempting to bring up the baby issue, especially if the big 30 isn't too far off. Some of your friends may even suggest making it clear on the first date that you need to start trying to have kids soon, because why waste time with someone who isn't serious about settling down? Just bear in mind that you might very well scare the girl off, since she can always put her eggs on ice and then marry some virile 25-year-old once she's established her career.

Just as we now look back with amazement at our blissfully ignorant ancestors who thought that smoking was good for you, or that a suntan was a sign of health, future generations will be shaking their heads at our blithe and all-consuming addiction to the internet. Assuming, that is, that the human race survives long enough to realize that Facebook and Twitter are causing brain damage and turning the population into an army of ADHD-afflicted robots who may very well become incapable of propagating the species. Or so warns neuroscientist Susan Greenfield, who wants us to please, please think of the children.

We all need to do our part to improve life on this planet, especially during these troubled economic times when the gap between the haves and have-nots only appears to be widening with each passing day. Tinsley Mortimer clearly appreciates this: It seems she's made arrangements to have the makeup artists at Christian Dior—she's a Dior "Beauty Ambassador," in case you weren't aware—give makeovers to foster children.

What happened on Larry King Live last night? Why was Larry panting over and fondling Levi Johnston's tattoo? What was with the creepy "sheep sex in the woods" undertones?

You can't Twitter meetings of the San Francisco Bay Area Rapid Transit directors any more, because someone recently threw red paint at one of the gatherings. That's fair and logical.

The idea of a book of microblogging "tweets" really bugs some people. Our own Nick Douglas, author of the forthcoming TwitterWit, already knows that. Now a New York Times columnist is feeling the hate.
