Though I haven't had it myself, I have friends who have. For those who don't read the whole article, at least keep these basic points in mind:

MRSA is an immensely antibiotic-resistant bacteria that has essentially grown in hospitals, nursing homes, and clinics. Since it is constantly in an environment with so many antibiotics, it is impossible to remove with standard antibiotics and requires much more advanced treatment.

You are doing your body a mean deed when you ask for antibiotics for every inkling of a cold or flu you get - this is fairly common in doctors' offices, but colds and flu are viruses and can't be shut down by antibiotics. Instead, whatever bacteria you have becomes resistant to these medicines and if you get say, bronchitis or strep and you need those medicines they might not work.

Some people also call these staph infections - the ones discussed in the article are called "CA-MRSA", or basically community strains of staph which are genetically different from hospital ones, and spread to people who have never been exposed to hospital MRSA. They can be dormant for a long time, and triggered when the immune system is particularly weak. They also apparently have a nasty habit of re-occurring.
