C-SPAN taking its digital roots further into the District with Foursquare may not sound important, but it’s fantastic news for trivia nerds.

The cable channel’s reason for joining the geo-tagging service is simple enough: be ‘friends’ with C-SPAN. Check in at a certain D.C. venue and get a bit of history. If you check into the Washington Hilton, you’ll get a prompt to watch the 2010 White House Correspondents Dinner speech from President Obama. The plan, according to Fishbowl DC, is to further expand  C-SPAN’s Digital Bus to tag political locations across its U.S. Tour.

Of course, it’d be just as nifty to learn some history depending on where you’re near–such as getting a nudge to go past the old Yenching Palace address in Cleveland Park that closed three years ago and helped end the Cuban Missile Crisis. Or if you happen to be at Good Guys, find out about the Russian spy who escaped through a bathroom window and ran up Wisconsin toward the Russian Embassy.

So friend C-Span and hope they start adding more of the fun side from the Beltway gang.
