When you apply for a job, what do you hope that will make you stand out of the crowd? Sending your resume and cover letter is fine, but so does everyone else.
Why not make a stand? Why not be amazing? Use social media to engage. Use creativity and online tools to get noticed. Be different.
Of course, there are companies that will not appreciate that kind of approach. They will not like people that are different, that disobey social norms or that challenge the status quo.
But do you really want to work for such a company?
And for companies: Can you afford not to hire someone like this? Do you really need just another cog in the machine?
