Hillary Clinton has finally joined Twitter, and her social media debut could have far-reaching repercussions for the future of American politics.

"Thanks for the inspiration @ASmith83 & @Sllambe - I'll take it from here... #tweetsfromhillary," Clinton wrote, referencing both the popular "tweets from Hillary" Tumblr memes and their creators.

The fanfare was intense and immediate. Clinton snapped up more than 350,000 followers overnight, a number that dwarfs most other political personalities and continues to climb.

Of course, a simple tweet doesn't guarantee that Clinton will cash in all this attention for a presidential run. But if Clinton is going to run in 2016, this is exactly how her campaign would begin building momentum.

Clinton is media-savvy, and Twitter is a medium that values wit and a biting sense of humor. Clinton's Twitter bio, limited to 160 characters by the site, lists her political accomplishments, as well as her fashion sense, her personal life, and her future aspirations.

"Wife, mom, lawyer, women & kids advocate, FLOAR, FLOTUS, US Senator, SecState, author, dog owner, hair icon, pantsuit aficionado, glass ceiling cracker, TBD...," it reads.

That's first lady of Arkansas, first lady of the United States, Secretary of State and "to be determined." And while the tongue-in-cheek references to her oft-reported hair styles and business attire show she isn't above a little self-mockery, it's the other points that are garnering the most attention.

Clinton was the first female senator from New York, which certainly qualifies as glass ceiling breaking, but her most famous use of the term came in 2008, in her concession speech to Barack Obama for the Democratic presidential nomination.

"Although we weren't able to shatter that highest, hardest glass ceiling this time, thanks to you, it's got about 18 million cracks in it," she told her supporters, referring to the number of votes she received in the primary.

And that callback to 2008 makes the trailing "TBD" sound much more certain than it might be otherwise.

The only thing certain at this point is that Clinton hasn't yet made up her mind about a run at the presidency. But loyalists (and anyone hoping for a guaranteed Democratic victory in 2016) can rest assured that she hasn't ruled it out.
