At 2:12 p.m. ET on Tuesday, Yahoo! Sports sent a tweet to NASCAR driver asking him about his use of Twitter.

"What does Twitter allow you to do/convey to fans that you can't in a press conference?" we asked.

Four minutes later, he responded.

Tweet No. 1: Show emotion/authenticity.
Tweet No. 2: Not rely on traditional media to tell ur story.
Tweet No. 3: Engage the fans directly. Etc. Lots of things I guess

Things like holding his own "Twitter" press conference, which Keselowski did recently, and revealing pictures of his broken ankle.

Follow us on Facebook and Twitter to read them first!

During a test session at Road Atlanta on Aug. 3, Keselowski lost the brakes in his No. 2 Dodge, slammed into a retaining wall at 100 mph and had to be airlifted to a nearby hospital. While there, he tweeted photos of his injured ankle:

In an era when little trust exists between athlete and reporter, when one clichéd response follows another, Twitter has provided athletes with a forum to be raw, original and, oh yeah, relay information at the speed –- 5 minutes ago -- that we want it.

And possibly no sport is revealed via Twitter more than NASCAR's Sprint Cup Series. With only 43 drivers on the track every week and about a dozen of those on Twitter, finding out what's going on behind the scenes and inside the heads of the athletes themselves is sometimes as easy as logging on to the web.

(NOTE: In May, Kyle Busch was ticketed for driving 128 mph in a 45-mph zone. The photo included in the tweet is a picture of the car he was driving.)

Two hours after responding to our tweet, Keselowski tweeted his whereabouts. You can see the proof here. What's interesting is that in his tweet, he says he was testing at Martinsville Speedway -– a session that went from 8 a.m. to 5 p.m. So we asked him: Did you respond to our question from inside your race car?

A minute later he responded.
