My web site generated a few leads over the years (first post in 2007 I think) but not many, not enough for me to live on. I think a few high-profile people get sufficient leads from their web presence but most of us probably won’t.

Anecdotally I don’t think the people who hire me read a lot of programmer blogs.

I get almost all freelancing work through referrals/word of mouth. About ten years ago I went with an agency that still represents me, and that has proven more reliable than my own efforts at self-promotion.
