Where have I gone wrong?

I'm now into my third year of running the most unpopular blog on the internet.

Total number of unique visitors (since March 10th 2002): 7,558
Average visitors per day: 10
Highest number per day: 41
Average per week: 66
Highest week: 152
Average per month: 290
Highest month: 557
According to Google, I have 41 inbound links.

I'm so very tired of hearing bloggers complain that they "only" get 30 to 50 visitors per day. Anyone have any secrets to share on building readership in this medium? I realize I don't have the most winning personality in the world (story of my life), but I have a feeling there is some other fundamental problem here.
