I love blogging and social media, and I have profiles on just about every social platform you could imagine. However, I spend the most time on my personal blog, Twitter and Facebook, so I'll link you to those and a handful of others.

In addition to these, I manage numerous other accounts for various businesses, mine included. I've done everything from writing blog posts and creating link bait to designing custom Twitter backgrounds and ghostwriting. It's pretty safe to say that if it involves social media, I know what I'm doing.
