Though the USA's current presidential administration does seem to be more science-oriented than its predecessor, the correlation between that and the President's own geeky nature and background is oft overlooked.

Obama's familiarity with Superman's legacy is evident not only in the picture Hodgman presented, but also when Obama roasted McCain some months ago. The President has since appeared in several comics of his own, including not only Spider-Man, but also an original title that segues perfectly with Hodgman's slideshow.

However, as proud as I am to have a geek president, I think we need to consider the image that Hodgman reinforced. It was just a decade or two ago that geeks were shoved into lockers, had sand kicked in their face, and never, ever got the girl. To hear Hodgman speak, those days are still with us, and the lines are still sharply delineated as the jocks-and-geeks war rages on.

In reality, as society becomes more technologically dependent, the geeks are inheriting the earth. Those who know how to use Twitter aren't just sharing lolcats; they're helping the Iranian revolution. Playing video games does not make us geeks; that activity has gone mainstream. Some of us would just as soon go for a 150-mile bike ride as we would watch Star Trek.

So if not the classic stereotypes of yesterday, and not the extremes that Hodgman parodied, then what defines the modern geek?

For that, I'll let geeks speak for themselves:

That day may never come, as that show's actors have mostly aged and moved on, the set dismantled, the public ready for something new. But diehard fans can be very un-Vulcan-like in their passion for these memorable characters. For them, the animated series Family Guy offers a special reunion in this Sunday's episode that reunites the bridge crew of the Enterprise-D:

Trek lore is rife with tales of on-screen characters played by actors who loathed each other, and it's refreshing to know the cast of TNG is not immunue to such petty rivalries, even twenty years after the show's debut. Their seven-year mission must've been laced with false politeness that just barely masked their contempt for each other:

(Hat tip to Levar Burton)

It can be fun to look at the making of Star Trek: TNG as it was actually being made. Without the benefit of hindsight, documentaries that are as old as the show they're inspecting have a certain nostalgic quality. And who brings that magic to life better than LeVar Burton, host of Reading Rainbow?

Before (and while!) he was Geordi LaForge but after Kunta Kinte, Mr. Burton hosted this PBS children's educational series that explored the power of books, fiction, and imagination. He took advantage of being an explorer of both space and imagination when he brought the show he hosted behind the scenes of his "other" show. Now available on YouTube as a three-part series is that episode of Reading Rainbow.

So open the video — and open your mind.
