Once merely a microblogging tool that allowed users to send out messages in 140 character chunks, Twitter has become so much more. As a slew of professional athletes demonstrated in the past year, Twitter can be a virtual marketplace, a boxing ring or a dating service.

Need to sell a dog? Twitter. Need to land a date? Twitter. Need to score some of those amazingly delicious Krispy Kreme Burgers from the Wisconsin State Fair? Well, you get the idea.

Here's a look at how some of our favorite athletes used Twitter to get what they wanted (or what they needed) over the past year. For a look at the best individual tweets, see here.
