If you are responding to a blog post then please use the comment facility at the bottom of every article. I read every comment and manually publish them all within a day or two (as long as they are not just marketing spam.) If your post contains questions that I can answer, I will get back to you as quickly as I can.
By far the best way to get in touch with me for any other reason is via email.
You can reach me at email@example.com
