After reading a lot about troubleshooting, I think I screwed up the aeration process. I didn't aerate my wort at all before I pitched my yeast. After I figured that out I opened the top of my fermenter to let some air in, covered it, and then shook the crap out of the bucket. A few hours later I began to see activity in the airlock, and two days later it is still showing a little activity.
Since I compromised sanitation with this batch of wort, I won't be bottling it. Its a waste but I needed to see if that was the problem.
