My blog also doesn't get too much attention. And it was always like that. I was writing in a couple of places, a couple of my blogs, and on a corporate blog. My most successful blog post had about 10k of visitors across the first year.

I also noticed that the average session time is about 2 minutes, sometimes is just too short to read through a blog post. So I assume that people come there just to get a solution to a problem they have, not to read through all the text.

Another thing is that over 70% of my blog entries are from two posts, a tutorial like ones. And this is only because someone found them informative enough to place a link on stackoverflow, and some other places.

At the very beginning I wanted to earn on the blog enough to work only on the blog. In reality that's impossible for a technical blog, and instead I just treat it as an interesting part of my CV.
