who am i what do i do?

Basically to describe what I do:

Well, lets put it this way I get paid to play with/test them also. In this industry there is not many networking meetings/conferences I miss in my area, in fact I'm trying to figure out what to write/present for my first speaking engagement at one of them. Mainly social media, search engine marketing, and search optimization are fairly new beasts to most businesses and CMOs, so I spend hours 24/7/365 teaching myself new techniques and learning old ones from other people. Trial and error, the good old hypothesis methodology, read blogs, write a blog, watch podcasts while I work (good ol' multitasking), and then I join hundreds of social networks, test them, build full profiles, and use them. If I like them I keep using them, if not then I just keep them up in case they change so I know what their useful features are and how to leverage those features. Then company's come to me with a goal, tell me they found me on one or 5 of the 300+ social networks I'm on and ask for help. I set up the networks, make a plan for tracking, and give them easy ways to join in the fun.
