I got two posts published on Triple Pundit last week:

Why didn't I post it here? Well, I kind of didn't realize it had gotten published. You see, you have to submit an article before it actually gets approved, and well, I kind of got caught up in other things. But here you go, two articles about the sharing economy, pretty fun stuff.
