re: smog media contributor, it kinda catches a few miscellaneous contributions, fex i think running the youtube channel (although this is a part of the smog proper now, so maybe this is a bad example) and the facebook page are recognised as media contributions
by and large, though, it is earned by writing articles for the smog on a regular basis. as to how you get into that, you'd need a decent amount of expertise in your chosen topic, and for the editors to get behind your choice of article
