My blog is not paid content. It’s completely free. + And I’m not linking to my blog for every answer, your comment is unfair. I think you should not police every answer with a link as an opportunity to warn people.
If I can give links about Go Blog etc, I should be able to give links to my blog when it’s relevant. If you’ve a blog and relevant content, I believe you may also give link to your own blog. There’s nothing wrong with that as long as it helps people.
